Even if I’m not too much of a Christmas fan, no occasion to spread joy and happiness should be neglected, so here’s my very own christmas card.
Depending on when you look at the card, the colors will be different. They are computed based on a section the current timestamp, as shown here. The gradient starts with a color at (red, green, blue) and stops at (blue, red, green) which gives surprisingly nice colors most of the time.
