Lisa built this base for a small potted tree many years ago, and I've shown it here before. There are control connectors built into the side that allow you to run a train on the (admittedly very sharply curved) track around the base and/or control the intensity of the lights on the tree. Complimenting the lights are origami cranes, so Lisa called it a Shinto Christmas tree.
I got Lisa some new tights, and she gave me a new leather holster for my mobile phone. She made the holster herself, and it's very nice and feels more secure (and thus less lightly to let my phone go shooting out the way it did more than once during the Iceland trip) than the one I previously had.
