Greg Erickson wrote me about these nice handmade wooden Sudoku boards he is selling. Looks like a nice Christmas gift!

A sampling of election night Twitter traffic that I was able to geocode. These are tweets that include the word “Obama”.
The arcs are tweets that were directed at another person. The blue circle is the source, and the green circle is the target.
Purple dots are tweets that were directed to the world at large.

I’m temporarily turning off a lot of the ads on the site, since Google’s competitive ad-filter is not fast enough to get rid of these abhorrent “Yes on Prop 8″ ads that have infected the site today.

I’ve been playing with a version that Native Instruments sent me, and it’s pretty cool!
If you’re interested in getting Animated Circuits, you’ll also need the latest version of Reaktor [...]

A few readers have written to me in the last few months, requesting Killer Sudoku puzzles, so I’ve been feverishly working weekends to get some ready for the website. They are just about ready to go, and I’m ready to pass out samples.
Killer Sudokus are an interesting hybrid between the Sudoku and Kakuro puzzles [...]

In a recent comment here on KrazyDad, Daniel Piker shared some flash variations he made recently of the John Whitney-inspired “Incremental Drift” animations used in my Whitney Music Box.
These are all visual eye candy, without music, but they demonstrate some great flash animation techniques!
