I am doing a bit of site redesign as my CSS skills improve. All of this is a prelude to my pending attempt to move this entire beast over to WordPress, a goal mainly thwarted right now by trying to preserve all the permalinks at the same addresses.
Anyway, I have a new page with all my published books and Powerpoint presentations here. I have a page collecting all my videos here. Since YouTube crunches all the videos to a resolution too small to really read my charts well, I have also set up a streaming video site with full resolution videos here. All of these sites are easily reachable by the new menu bar across the top of the site.
