A while ago I completed my own prototype Transformers toys. I made them just for fun (and practice). These are Audio cassettes that fit inside the toy Soundwave, stand on their own, and fully transform. They both are original designs, sculpted in wax, and cast in color tinted plastic resin. For those unfamiliar with these types of toys they are around 1 1/4" X 1 3/4" and about 1/4" deep, fairly small (and super thin!). I was just posting pics of them on various forums looking for crits and such.
Neither toy has a name yet...

If anyone is curious, I can post about techniques used to make them.
