[There was a video here]

The Gizmodo App Challenge inspired by BMW i's sustainable and design-conscious i concept cars came and went, and one talented Gizmodo reader had her winning app revealed on Wednesday evening at the GQ Best Stuff of the Year event. The winner? "I Can Make That," a creativity a sustainability app created by Sara A. that helps people repurpose materials lying around the house by making DIY projects out of them (like turning an old bicycle into a pedal-powered generator for camping).

What did she win — besides the big reveal at a decadent event? $50K in development services from our friends at Detroit Labs. Pretty sweet.

Head here to check out the other finalists in the app challenge, then flip through the gallery above for photos from the night and a peek at the video we created to convey the winning app's brilliance.
