Siri Meets Eliza

Since I got my iPhone 4S, I’ve been intrigued, fascinated and alarmed by Siri’s fast-growing capabilities. I thought it would make sense to introduce her to my psychotherapist, Eliza.

ELIZA was one of the first (and longest) BASIC programs I typed into my then brand-new 16K Apple II in 1979. Originally created at MIT by Joseph Weizenbaum in 1966, this pioneering natural-language-processing simulation of a Rogerian psychotherapist impressed my family and friends every bit as much as Siri does now. I was curious to see how they would get along.

Here is a transcript of their first encounter. Despite their 45-year age difference and two-million-fold disparity in RAM, I thought they understood each other remarkably well. Continue Reading

The Prince of Persia ebook

For readers who’ve gamely clicked their way through all seven years of my “Making of Prince of Persia” journals online — and those who haven’t — I’m happy to announce that the complete saga is now available as a PDF and Amazon Kindle ebook.

The book isn’t free — we’ve priced it at US$7.99 — but at 300-plus pages, I hope it’s good value. We’re publishing it without any copy protection or DRM, so pirates shouldn’t have much of a challenge. Book sales will help defray the costs of this project and of maintaining the website.

The ebook contains the original Old Journals, plus never-before-published entries leading up to the beginning of The Last Express. You can download a free sample PDF of the first 40 pages, or the full ebook, here.

Thanks to Danica Novgorodoff for designing the book (Danica is the multitalented author of the excellent graphic novel Refresh, Refresh, and designer of many First Second books, including Solomon’s Thieves), and to David Anaxagoras, Ryan Nelson, and Aaron Simonoff for their hard work putting it together. It’s safe to say it turned out to be a lot more work than any of us expected.

How Prince of Persia got made — and almost didn’t

In the ebook, you’ll read what I wrote in my journal on the day I videotaped my kid brother running and jumping to model the prince’s moves; the day I gave up on the project; and the day I decided to finish it after all.

In the seven years from May 1985 to January 1993, Prince of Persia went from a few scribbles on yellow-lined paper to a published, best-selling video game franchise, and I changed from a callow kid into (I thought) a seasoned software entrepreneur. If you’ve read the journals, you know that it was a bumpy ride, and that the game’s eventual success was anything but a foregone conclusion.

Whether you’re a game designer or in another creative field, whether you had an Apple II in the 1980s or weren’t born yet, I hope you’ll find inspiration (or something else of use to you) in this story of how one game got made.

Check out the ebook here.

A request

This ebook is an experiment in many ways. I have no idea how many people will be interested, or how well the non-DRM “honor system” will work. Either way, I’ll post once the dust has settled, and let you know how it went.

If you’ve enjoyed the Old Journals on the site, but don’t feel the urge to own the ebook, you can still support this project by helping us spread the word. Readers like you who take the time to post or tweet about the Old Journals ebook, review it on Amazon, or just tell a friend, will make a big difference in the experiment.

Many thanks!

R.I.P. Steve Jobs

The news of Steve Jobs’ passing hit me in much the way John Lennon’s death did in 1980 — I mean it blindsided me and my whole circle of friends with a surprisingly personal sense of loss although we’d never met him.

And not just because we heard the news — and shared it with our friends — on the iPhones and MacBooks that our fingers touch, on a daily basis, more than practically anything else.

Apple’s products have changed the course of my life, as I’ve previously written. But I admire Jobs most of all for three reasons that have little or nothing to do with the MacBook I’m typing this on:

  • He got fired from Apple. Kicked out of the organization he’d devoted his life to building. I can only imagine how that must have felt. Yet he came back from it in a way that said: “That wasn’t my life’s work, it was just the overture.”
  • He bought Pixar from George Lucas when they were down and out. He put his own money on the line,  then doubled down, buying into the dream of computer-animated features at a time when nobody else would.
  • He gave one of the best commencement speeches ever, one I’ve often returned to when I’ve felt the need to adjust my frame of mind. He said things like this:

“Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure — these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.”

Jobs was no plaster saint. He shares many traits with Henry Ford, Thomas Edison, and Walt Disney, and will take his place in history books (or history ebooks) alongside them. Like the co-founder of that other Apple, John Lennon, he was, is, and always will be an inspiration.

Awesomest travel sketchbook ever

The amazing husband-and-wife artists LeUyen Pham and Alex Puvilland (my collaborators on Solomon’s Thieves) recently participated in a project called “sketchtravel.”

It’s one sketchbook with a bright red cover that’s traveled the world for over four years, passed from the hand of one artist to another — literally. Shipping the book in the mail, or giving it to an intermediary, is not allowed. Each artist gets a few days to do a “sketch” in the book. No do-overs, no mistakes.

The sketchbook eventually reached over 70 artists, including such living legends as Quentin Blake, Hayao Miyazaki, Peter de Seve, Carlos Grangel, and Tadahiro Uesugi — and, I’m proud to say, LeUyen Pham and Alex Puvilland.

Here’s Uyen’s page:

You can read more about the project at www.sketchtravel.com.

The original book will be auctioned in Brussels on October 17th, with proceeds going to a charity called “Room to Read” that builds and furnishes libraries for children throughout the world. I really, really envy whoever gets it.

For the rest of us who don’t come up with the winning bid (I think it starts at something like 20,000 euros), a reproduction of the book is being published by a European house called Chêne, and can be purchased through amazon.fr. There’s also a super deluxe collector’s edition complete with a wooden box.

Pre-ordering mine now.

Voice acting for video games

In today’s guest post, Yuri Lowenthal (who voiced the Prince in 2003′s Prince of Persia: The Sands of Time) talks about the special challenges of voice acting, as opposed to acting on camera.

When Yuri, Joanna Wasick and I came together in a sound studio for the first day of voice recording on POP:SOT, we didn’t have animations, animatics, or even concept art yet. While the POP team was bringing the world and characters of the game to life on screen, two actors first needed to make them real in their imaginations. The Prince and Farah began as voices in darkness.

I cherish voice recording as a special, thrilling, and terrifying moment in game production. Having experienced it from a writer-director’s point of view, I asked Yuri for an actor’s perspective on the process.

Yuri Lowenthal is an actor who lives and works in Los Angeles. You may have heard/seen him in Prince of Persia: The Sands of Time, Afro Samurai, Terminator: The Sarah Connor Chronicles, and Ben 10. He is married to actress Tara Platt and easily stalked at @YuriLowenthal. And if you’re nice he’ll tell you the exciting story about the time he met Jake Gyllenhaal.


People often ask me: “What’s harder? Voice acting or real acting?” I’ve heard it so many times that I hardly get offended anymore. Almost hardly. I mean, I get it; the person speaking is really trying to say: “What kind of acting is more difficult, the kind where we just end up hearing your voice, or the kind where we end up seeing your face?”

Well, let’s break it down:

For on-camera acting, I generally get the script in advance, time to talk with the director about the character and what his or her vision is for the project, maybe do a little research, put on a costume, work with some props, walk around the set, rehearse with other actors, and take time to break down the script so that I can bring you, the viewer, the best performance I am capable of.

For voice acting, I generally show up the morning of the recording, am handed a script, and after about 5 minutes (if I’m lucky) of discussion with the director (or sometimes writer) about the project, we get down to business so that I can bring you, the viewer/listener/gamer, the best performance I am capable of. Will my performance be judged less harshly because I didn’t have the niceties that an on-camera or theatrical situation can afford? Absolutely not. Continue Reading
