I really like the fluids that I've seen used so far. I have an idea for fluids where you have a canvas, paints and a brush and move the colored paint fluids around with the brush, creating a painting in VAM. Maybe the brush "spits" the colored fluids out. You can paint on walls, floors, objects, and of course also on people. The fluids can stay on the canvas for a time or they can fade away after a short while. Just a thought that I think would be a cool and creative feature to add.
