In MTH 221 we also work with tessellations but to a different extent. In MTH 221, we took a square, cut piece(s) out of it, then reattached them somewhere else on the square. This topic was covering the different types of tessellations so we created two different shapes. My first shape was created using slides. From this, my shape resembled the Teenage Mutant Ninja Turtles. My second shape was created using rotations. This shape resembled distorted bats, so I colored them Halloween colors. I wish I had my past school stuff with me so I could post a picture, hopefully I come back to this with an update.
For MTH 495 I first started using the pattern blocks to create tessellations. I later moved to the isometric dot paper. I think overall I probably spent 3-4 drawing the page. Obviously there were distractions but I watched two movies while doing the drawing. Below of pictures of the beginning and the in progress. I'll updated with the completed colored version when it's finished.
I also really enjoyed this website that allows you to create patterns online. I wouldn't be able to spend as long on a site versus doing a tessellation with pen and pencil but it's still an excellent resource and a good time killer.
