Yes, I decided there weren't enough fractal puzzles here at puzzlepicnic.com, so I made one.
You can think of the puzzle as being created in the following way. Start with just three nodes arranged in a triangle. There's exactly one way to form a Hamilton cycle through this simple maze. Now replace each node by a new triangle. For each of these triangles, you know from which other triangle the Hamilton cycle must come in, and to which other triangle it must go next. Again, there's only one way to meet those requirements. If you now replace each node by a triangle one more time, you end up with the maze I made, but of course, you can repeat it as often as you like!
