You can be creative and hide it. Or There is a cheaper version using AA battery instead, however, it will be a bit cumbersome cuz you will have to change the battery for each one.
I can't really see the main purpose of having this gadget. The light is pretty dim to light the whole room. If this is just a toy for children, I will definitely say it's one of the worst idea. Children keep looking and playing lights will have bad effect on their eyes. Also if I need to touch the whole wall again to turn it off, this thing is pretty annoying after using it twice. Perhaps in the future you can have the programmable version where you just need to touch once and all light will turn on with customized different color.
