The Aborigines have symbols that communicate meaning in their art. A single arch symbolizes a person, concentric circles are a symbol for water hole, diagonal lines represent rain, and arrows can be spears or emus. Acrylic dot paintings became popular in 1960's, but dots are used to create ancient rock art as well.
A lot of students chose to use black or another dark color as a background to provide contrast for the lighter colors. We dipped unused pencil erasers into house paint to make the dots.
The student who made this painting has prosthetic eyes. The latex paint dots and puddles were somewhat tactile. When she felt her painting the next day she said, "Oooooo. This is really nice!"
