http://autodizactic.com/blog/?p=1514 This is the kind of activity I can really get into. Perhaps *too* into. During my first year as a teacher (2003-2004), the district passed a bond issue and made plans for a new high school. They had some rough sketches, but they asked the staff to think about what features they would like to see in the school. I started sketching on regular paper, then moved to graph paper, and eventually became so obsessed with this project that I taught myself CAD and drew out floor plans for the entire school, one big enough for 750 kids. Thanks to a little bit of inspiration from Zac's post, I dug up those plans and posted them to by blog at http://blog.mathed.net/2011/11/designing-school.html.
