Kerning is the sort of thing you won't notice until someone tells you what it is, and then it will make you miserable for the rest of your life. There's a surprisingly well-made kerning game. It is not as easy as it looks.
I talked about De Stijl yesterday. Piet is a programming language whose programs can look like De Stijl paintings, although you can see from the samples that people have created all kinds of patterns, like the giant red circle that calculates an approximation of Pi, or the 'Hello World' that looks like the world.
Every issue of De Stijl Magazine in PDF form. I can't read Dutch, but the visuals are incredible.
