If you’re willing to help, sign up to be notified at the site. When the kid is born, Will will light-up the email/sms Batsignal to notify everyone, and then you’ll use your cell phone, video recorder, laptop, pearlcorder, etc. to capture some sounds from your world. Then you upload them. There’ll be a form-based interface for you to upload your sounds, along with lots of meta information like location, time, description, etc.

Short-term, Will’s going to build a Google-map API hookup and whatnot, with Flashy bells and whistles, to plot the received samples across on a world map and give contributors an interface to explore the results of the project. Long-term that’s probably not too future-proof, but he’ll try to maintain and update it over the years. Eventually, when the kid’s old enough to care—which is probably sometime around the year 2030—it’ll be something cherishable.

Eh, just go there and read Will’s explanation. So far he’s had about 100 sign-ups, which will probably translate into 30 actual participants or so, if we’re to be realistic about things. Hopefully there will be some far-flung, globe-spanning submissions. It should be fun and interesting to hear the results, not to mention satisfying, knowing that your sounds will be part of a time capsule being sent to a kid 20-odd years into the future. C’mon, help out.
