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:

How can I loop through each pixel in an image and get their red,green,blue values?
I also would like to be able to create a new image using those values (modified, for example set red=red*0.5)

I know Karl did a great project Color Reading And Writing which I could use, but would like to introduce some of the kids to squeak.

Thanks,

Stephen
