Tiling with a PocketSized xyPlane One area of recreational reserach of mine is investigating the symmetries of point sets in the plane (eg. graphs of functions) under a particular transformation which maps the entire real line onto an open interval of length 4. In January of 2006, I presented some preliminary findings in a Math Club talk. Below I include the talk announcement and abstract, originals of the transparencies that I sketched upon during the talk, and (page by page) the images that I sketched during the talk. Please contact me if you find this interesting and would like to share in the investigation! Announcement and Abstract
