Ducks at Phoenix Zoo with stage-4 Sierpinski tetrahedron, taken in February 2001 (in the drawing, the Sierpinski Tetrahedron has been changed to a stage-2). The tree in the background is an Oldham Bamboo, aka Timber Bamboo (Bamboosa oldhamia). Print drawing on "Landscape" setting, found under "Page Setup" or "Print Options." One thing missing from this drawing is a fence.
Scarlett macaws at Phoenix Zoo with stage-4 Sierpinski tetrahedron. The macaw at top was in full wingspan only moments before I snapped the picture and I missed it! That is why, if you will notice, its feathers look so ruffled. The colors in the tetrahedron that appear to perfectly match the macaws are Cadmium Yellow Light, Napthol Red Light, Cerulean Blue Hue, and the green is Deep Permanent Green.
Drawing needs some trees and background detail.
Toucan at Phoenix Zoo with stage-3 Sierpinski tetrahedron, taken in March 2001. If you look, you can see my fingers at the right holding the tetrahedron in front of the camera. Drawing needs some touching up, especially the tree up top!
Taken at the Phoenix Zoo. The flamingos show up very well in this picture, much better than the icosahedron. I've included it here because the birds are interesting to look at, and may be fun to color as well.
