When I was a kid, I could not be separated from my Spirograph set. I could sit for hours and create shapes, experimenting with all of the different pieces, though I wasn’t able to create anything other than a mess with the football shaped piece. And I was never able to wrap my mind around what exactly the oblong piece was for. Little did I know that I was creating mathematical curves!

Naturally, I got a huge grin on my face when I came across these Spirograph cards from Blackbird Letterpress. Boy, do these cards bring on the nostalgia. I even recognize some of the shapes, which were created using a vintage Spirograph, as being very similar to those that I made as a kid. Blackbird’s are better, though, and they’re letterpressed! $12.95 for a set of four.
