I was so impressed by this DIY project, to use common materials found in people's homes, a camera and some open source computer programs to get said items into the upper atmosphere to take photos of Earth!
Read about it here on Wired.
The college students who did this will be sharing a tutorial for free, so anyone else can do this.
I showed this to my kids and it blew them away. My twelve year old engineer wanna-be wants to do this right NOW.
Hooray for the geeks!
