This is an example of making a small binary drawing, and then uploading it to a cloud variable. The entire drawing is represented as a binary version of the pattern -it turns out that the largest int that Scratch accurately represents is less than 2^64, but larger than 2^49, so I went with a 7x7 grid for the canvas. When you "Begin", first click on "Download" and see what it on the cloud. Then, you can make changes, and "Upload". "Upload" is disabled until you "Download" to see what others have done. Then, you can change it, and do an "Upload". Then, other scratchers will see that drawing.
