Great Examples!
Eagle DuraSig Five-Section Flashing Yellow Arrow, that's an interesting one! I have never seen such a thing like that...and often if that dog house was found on left lane the arrows are on the left side, but if it was on the right lane and arrow was to turn right, it tend to be on the right side of the traffic light feature.
Great job on the animations, you also seem to be a good artist on very specific details using the paint brush, the open source program of GIMP (which I also use) and the Microsoft GIF Animator (a really OLD OLD Windows 95 program!) I also use my Macintosh (which finally I am getting fixed for FREE OH JOY OH JOY!)
Cool man!
