Jonathan and all-BICAS has been building custom sculpture/bike racks out of old bikes/parts/scrap metal for many years. Now they are a point of pride for small businesses all over Tucson, and get a lot of great publicity for BICAS. They are pretty simple to build with a welder and a chop saw/grinder, 'cuz they look awesome no matter what, and can be a solid supplementary income for any bike project that has the facilities/inclination (those prefab ones, though slick looking, are kinda pricey). Lastly, it is a good destination for some of that stuff that just can't be useful as a rolling machine any longer. I'll try to send photos to the wiki soon.
Thanks for the post/ wiki Jonathan; good idea.
