Has anyone tried using the projectors for decorating that are sold in craft stores such as Joann's?

I have heard of a few who have tried them.They are table top and shine on to the wall...One video on You tube shows how a cake shop mounted theirs on a homemade built stand to use it standing up but I have a kopykake one anyway..Best investment for me since I do alot of kids cakes.

Do you happen to have that youtube link?
