As the mixed-media name implies, Tim covers a lot of ground, both personal and universal, including video, shrines, portraits, and large-scale projects that have a political edge, like mapping of nuclear test sites. The project he's posting on his blog now is from a series of portraits called "Extraordinary Rendition." It's been up for a few days, so you may need to scroll down to see the first few stages.
Here's a shot of Tim with one of the finished drawings in the series, appearing at the Bemis Center for Contemporary Arts in Omaha last year. So you can see the scale.

And don't forget to try the nifty Baconize function! Especially useful if you missed breakfast.
