Almost everyone has heard of the Spirograph, but few people remember the Spirotot, a simpler version designed for toddlers to use.
Unlike the original Spirograph that contained a dozen or so small plastic discs for children (and adults) to choose from, the Spirotot rolled everything into two or three discs. The base of the Spirotot snaps into place and keeps the paper from shifting around. I personally never thought that the original Spirograph was too difficult for children to use, but if you do, then the Spirotot is for you.
I recently found this Spirotot in a thrift store for almost nothing, and when I got it home I discovered why: the Spirotot discs are missing. Shortly after this picture was taken the whole thing went into the Spirotrash.
