Webcam images: For any number of reasons, the webcam is completely and utterly down (we moved). The image below was one of the nicest captured by the camera from our old house.
There used to be a wonderful bunch of pages here that reflected my progress in hunting for maximal caps in N-dimensional Set. Apache ate the page, but I've summarized some of the results below.
The relevant numbers for Set are 2 4 9 20 45 112 193 >330 >505 908. The later numbers are not quite good enough to be publishable :(.
The best basic summary of the mathematics of Set: "The Card Game Set".

There's one more link that was lost that shows that a few good theorists have made serious inroads into the higher dimensional problems.
The above images are either the output of my Set code (searching for maximal caps in 6 and 7 dimensional set) or some raw output from my Q measuring experiments at the University of Washington.
