neat optical illusion

[cellio]

Friday night while I was walking home I saw a neat optical illusion. The moon was full (maybe a day past, but I think full) and bright. The sky had clumps of fluffy clouds with plenty of gaps. The clouds were moving fairly quickly, together. The effect was that the moon appeared to be racing across the sky. Funny thing, perception...

And the halo linked up with Orion, when I saw it. Deeply winter. I should have taken a picture, but I'd have had to walk back to the car to get the tripod, and I was underdressed and cold.
