Experimental mosaic... or maybe a new mineral species?

This one started as a doodle. I began placing circles to see what kinds of complex shapes I could make, and this was the result.

It achieves a new visual effect at almost every size up to the original. Also try slowly moving the zoom slider for some interesting animations!

This font is now nearly 1MB in size! I guess it has to do with the intrinsic complexity of circles.
