Hi Steve,

I remember Kedama-projects from Yoshiki, where he modified individual pixels in an image. While I was looking for these projects, I found a very project from Mr. Dreyfus in our showcase, in which a sketch can be dropped onto Kedama and is converted into Pixels, which are then moved. You can find it here:
