I made this because I figured that (almost) all of my sprites would be bored if they were't in use. ;) Some of the sprites you might not recognize from my projects but that is because I a) never shared them, or b) deleted them. It is kind of interactive . . . Click and drag a sprite to move it around and press space to change the background. If you click and then drag the mouse over all of the sprites, you can move all of them at once!
I got the moving code from @GoldenMiru (Sorry—I should have made it a remix)
