lol @ aux's comment...
ive gotten shark fin...tooth, and wave, so far. it wasnt really supposed to be any specific shape. This assignment was mostly about the actual model..like you did the mold process correct. im stoked how it came out with the different relections/refractedlight... but i was going for some sort of wave/aquatic theme...
I could make a shift knobs now that i know how to do this silicone mold process...or on the lathe...which is more likely or maybe, auxilary, i could make you some specialty dildos if thats what you want.
