Yes, where are 24 and 25? They'll be running late as I've been on vacation with Tesla and Mie and never seem to have time to work on anything ...strange as that may sound. And this week's project didn't really turn out as well as I'd hoped, but hey I tried. And I still like the idea and can try to make it work better when I get back to San Francisco.
I'm a big fan of street art, and Buenos Aires is one of the most amazing street art scenes I've ever known. It has everything: wild style writers, tags and huge amazing pieces (see my flickr set for examples), but what it has more of than anywhere else I've known is stencils. They're everywhere. Last time I was in this city I got a grand tour of the past and present of the BsAs graffiti scene from one of its original practitioners. He told me taking photos of street art was fine, but I should also be creating it.
This time in Buenos Aires I took up the challenge. I wanted to leave a little San Francisco flavor behind, and what (or who) tastes more like San Francisco than Frank Chu? I have several of my own photos of Frank, and even one where I dressed up as Frank at Burning Man, but I started with a photo taken by Scott Beale because he takes better photos. I did some photoshopping and ended up with this image:

I printed this out and used it as a guide to cut out from a piece of cardboard. The letters were really hard to do as they were so small. When I tried to spray paint the stencil held against the wall, the small lettering smudged and the results were unreadable.

I still like this idea though. When I get back to San Francisco I'm going to change the sign to be more like Frank's (dense with lettering) and maybe have him impeach Gavin or Obama instead, but make the overall stencil much bigger and exact using a laser cutter.
I was thinking that really what I'd need to do a good stencil of a detailed piece this small is to use magnets against a metal surface (like a utility box) to keep the stencil very flat against the surface.
