The GorillaPod by Joby. I gave it to Don for Christmas last year. Small enough to fit in the pouch on the front of his bike, small enough for me to jam in my purse. I use it a lot with the legs just bunched together to help hold the camera steady, sort of like a short monopod.
Blogger seems happier today but I'm still not doing much Blog Wrangling for Don today. By the way, one of my official titles, other than Blog Wrangler, is Don's Handler.
