Octahedron Christmas Trees

Okay, there's nothing particularly Christmas-like about this pattern. It's just a vague depiction of a tree, but I chose to call it a Christmas Tree because of the season.

Woolworths used to sell decorations like this back in the 70's when abstract geometric shapes were the "in" thing.

Pyraminx Christmas and Hanukkah

This is a chance color scheme that appeared while I was toying with Meffert's 25th Anniversary Edition Metallized Pyriaminx. When the colors are permuted as shown the red-green sides suggest a Christmas color scheme while the gold-blue sides (roughly) suggest a Hanukkah color scheme.

The color scheme isn't a perfect match, but it's powerfully suggestive when holding the puzzle solved this way.

5x5 Curvy Snake

This is a 5x5 variant of the standard "snake" pattern from the 3x3 cube, but with curves added.

I made this pattern during a holiday in Hawaii and accidentally stumbled on the Tropical Petals pattern afterward. So the simplest way to create either of these patterns is to first arrange the edges as shown here for the Curvy Snake, then adjust the center pieces to match either the Curvy Snake or Tropical Petals pattern.
