Well I made a post this morning but apparently there are reasons why the human mind needs sleep in the first place! I ended up just sending it to myself instead of the list. Righto, try again!

Aww hell, I couldn't sleep so out of sheer boredom, and perhaps to the interest of someone on this list, I'll post a small version of that panorama that I just finished stitching...
Of course right after getting this film developed I realized that the big christmas tree wasn't lit up DOH. If it ever stops winding and raining then I'll have to go shoot it again.
