Well hey, 3 great ideas that I would personally buy. Cthulhu, Han and sunglasses are all great, but they need to be Cherry profile not those nasty tall Filco profile crap. Hmn... so something else? I guess I am not feeling very creative right now, but how about the Cherry logo in a 3D molded cap? Seems rather obvious... huge bonus if it could be pulled off in 3 color like red cherries green leaves white base.
I would also like to take this time to suggest you change the thread title to '3D/molded custom keycap designs' or something to differentiate from typical 2shot, dyesub etc styles usually covered in the other thread.
