Just a fun experiment to see if it could be done, a Random Dot Stereogram of a Julia Spiral, done in quadrium | prime. The answer would be "yes" (though this is actually a pattern rather than random dot, but a pattern allows for arbitrary resolution, which even works for the small thumbnail).

png is too large, jpg would be proper
Very awesome idea and execution.
It's hard to get at first, but I got it.
