Several weeks ago, I attended Startup Weekend here at Cal Poly and I worked on a project called Haberdash.
Haberdash is a clothing recommendation engine that makes clothing recommendations after building up a profile on a user. It is essentially the equivalent of Pandora but for clothing.
My job was to build the iPhone app over the weekend and it wound up looking pretty good during our final presentation.
We had an excellent team at Startup Weekend and wound up winning 1st place.
Here is a video showing what was created by the end of the weekend:
