I Goodwilled my full spectrum light set up when I left the Northwest, but with two weeks of cold rain in KC recently, I needed to take steps. These light therapy tokens are fun to draw and cost nothing. Staring at them has some kind of positive neural-ocular affect and combined with barbecue, will get you through. They would also look good as 20' x 20' heat applied graphics on the side of a building. Other than that, totally useless.
