Look what I discovered I could do with www.picnik.com!!?!!!
I found an image of a slightly messy chalkboard on google-images.
I uploaded it to Picnik.com.
I typed in some text and a few “stickers” and then faded them 30-40% or so from the orginal full-strength white and voila! I have no idea if I have any use for this in the future, but I did it. 5 minutes of good fun.
Happy ways to say “so long.”
Right-click on the empty chalboard at right and you can give it a go, too.
