The computer stuff is a great idea. I like the learning about batik prints, too.
One thing I did in my Art for Children class that I loved was listening to about 5 different songs in a row, and painting/coloring what I was feeling on a seperate piece of paper for each song, and putting them together with the rest of the class. We defined the mood of the song by looking at everyone's paintings of that particular song.
We could do crafts, or free events in the Dallas area, too.
Keep those good ideas rolling!
