[hackerspaces] Cool projects for TEDx talk wanted

[Mitch Altman]

Hey,

I'm writing my TEDxBrussels talk, which is due in a couple of days, and am wanting to add some example projects from hackerspaces in my talk, with a cool and/or weird and/or beautiful and/or cute (and/or otherwise eye-catching) photo for each.  

Anyone have any project (or know of any project), that has a photo that would impress non-hackerspace folks, and help the world take notice of hackerspaces?  If so, please send me a photo I can use, and a short description of the project.

Thanks!
Mitch.
