I'm fascinated by the photo mosaics created using Flickr's Montagr.  I think that I will try this, but I need to do it at a time when I'm not so very busy.  The last few weeks of school are jam-packed with activities for the students, reports to be made, books to collect and shelve, and many other end-of-the-year responsibilities.  Once things settle down, and I have a little more time, I'm going to do a little bit of exploration of the many new things I've learned.
