Good stuff. The second is very much my kind of thing. The third could go in the minimalist thread.
... and #3 is hilarious.
I like how the second one pulls me into it. What's fun about it, is I think it works rotated +/-90 or 180 too. Here's 90 to the right.
Ha! That works very well: if you could clone out the lights, it would be even better.
