Found it here.
Yes yes, it can be done for real nails. AWESOME!
This is called the Clever room. Ha can you figure out why I am showing it?
You can see it here.
I gave the nail painting a try. SO here is my pinky finger. Yea looks weird because I used shiny polish, as told NOT to do so I had to angle my finger weird to see the print.
BTW This is something Only for Adults. As you use alcohol to make the print stay.
