My students learn how to draw a few different optical illusions and then combine a few to create a landscape. They then use tempera neon paint and black to paint on 9x10in paper.
Definitely a big hit! Students drew out a plan before they were allowed to start using a half mask template or a whole mask template ( I drew one of each on copy paper and students could choose) We used plastic molds and strips of plaster (you can order them through Blick) that were dipped into water and then smoother over the mold. Depending on the design students either did two layers on the same day if they didn't have any embellishments, or one layer and let it dry, then added wire for horns, beaks or whatever, and added another layer. After a few hours of drying the masks easily popped off the mold. ( I found it better to take them off before they dried completely.) Then students painted however they wished. If they used the neon tempera I had them put a gloss acrylic medium over it.
If you haven't noticed...I haven't posted in a long time, but I have been taking pics. The problem was I didn't have the time to "transfer" the pictures from my school computer to home, so I could blog. In the mean time discovered the wonderful world of picasa. I didn't realize how easy it was to use! So today I am trying to catch up. Sorry to over load you!! But better all at once then not at all!
Students had a posterized image of an animal they saved and edited at http://www.picnik.com/. Then with a grid drawing transferred it four times (light table would come in handy). Really cool results. Took about a week of 1.5 hour blocks.
