Definitely getting into a building-stuff mood. That's tied in closely with Halloween in general, as most of the stuff that's making me excited about building is related to animatronics and people-sensing. I suppose I could back it off a bit to motion control-- making things move in a coordinated fashion controlled by a computer-- but there is a certain edge to Halloween time that makes me almost joyeaux.
I don't know why fall makes me feel a lot more creative in that way. Maybe it's just programmed in after years of spooky stories and tales of terror.
