Welcome to my ten square backdrop maker! All you have to do is press the arrow keys, and then take a screenshot when you like what you see! WARNING: SOME SQUARES MAY LOOK LIKE CIRCLES, I ASSURE YOU THAT THEY ARE INDEED SQUARES. IT'S THE THOUGHT THAT COUNTS.
Happy 100th SDS! By the way, to make the squares transparent, you can take a screenshot while holding the arrow key.
