Update 5/27/21: It's been nine years since this article was posted, and a lot has changed since then. With the proliferation of inexpensive WiFi-, Bluetooth-, and even cellular-enabled microcontrollers, these devices are no longer as interesting as they used to be. However, I still have most of those 30 Peeks, and I'm a lot more skilled at bare-metal programming now than I used to be, so I intend to do something with them within the next year so they don't go to waste. I'll post any project ...
