Yes, it really is a perfect "Koch snowflake" profile, if you view it corner-on. What, you didn't believe me?
A fractal cube-based solid with "Koch Snowflake" profiles and crosslike "box fractal" faces. Six "face-on" viewing angles give the "cross/box" view, and eight "corner-on" views show the Koch Snowflake outline.
It's a bit difficult to see the detail with WSF. If you like this, you'll probably prefer its "Koch Snowflake Sponge" sibling, which does just about everything this does, and a bit more, and should show detail better.
