Christmas Wrapping

 Every so often I produce an image in the JTS TestBuilder which strikes me as worthy of capture.  Here's one that seems pretty seasonal:

It is generated like this:

2. Compute their fully-eroded Convex Hulls
3. Compute the intersection of the two hulls
4. Theme the intersection with random fill
