Remember Spirograph—the drawing toy that let you use rotating discs and templates to make geometric art? We sure do—but with a hint of sadness, because we could rarely keep the discs perfectly stable for a whole drawing. Now Nathan Friend has developed Inspirograph, which re-creates the experience digitally: it’s like Spirograph, with better control (and a whole color picker’s worth of ink colors). And it is a lot of fun. Play with Inspirograph (and don’t miss the gallery of others’ creations!).
