Crazy Shorts: Insparation

Look at these shorts:

You probably think there pretty... uh... interesting, and so do I. But it seems in some subculture I've never seen, people think these are great. There are a couple of stores on Etsy, eBay, and even a "real" (self hosed) store who sell the shorts from $35 to $180. I want to try to get in this game. I think making these shorts looks like fun; I'd buy jeans from Goodwill and cut off the legs then go crazy with the hot glue/studs/bedazzler/dyes/bleach etc. I'm not sure how successful I would be, considering this again is a fringe market that already has established brands.
