It's been a while since last time I photographed snow crystals, so today there was a lot of joy in repetition.
The biggest challenge, in my opinion, is to get the lighting right. The crystal itself is completely transparent. It has a lot of angles acting like prisms, so with a combination of lights from different angles it can become interesting. This one here is an experiment with a piece of coloured cellophane and a flash, and a LED flashlight. Challenge for next time; do it more delicately. :-)
