Mini sculpture idea that I will not make...

My grandma used to have a bunch of erotic "chachkies."  whenever I saw them, I would get kinda awkward. Still, the experience stayed with me and now I am an older person myself.  idea I had at my job sorting through partial electronics:  make a little handheld sculpture of a naked male and female figure.  make them ergonomic like a video game controllers such that they would exactly, comfortably fit in your hand.  for example, the curves of the woman might mean that your thumb rested between her legs in order to have the sensation the it was properly fitting into your hand.  just an idea that came to me while heading to bed two nights ago.  these little sculptures would be useless.  the only utility would be to give you the sensation that they fit into your hand.  useless, pleasing, art?!?  is anything that is pleasing useless? probably not.
