I'm looking for a device that can push out independent pinpoints from something similar to a Pin Point Impression Toy. I'm looking to create a 3D image from for example my computer. Does anybody know the name of such a device or can point me in the right direction of making one?
I've been looking now for a while, but I'm having some slight problems finding a good way to describe it as a search term.
I'm sorry if this is the wrong forum.
