This MCG allows you to do marching ants, traffic light/direction effects. Note the Count is total in array but you see only every 'Step'. I think there is a bug with closed loop and Even count, so use odd Count for that....and WTF is up with the 90deg angle/rectangle ? Dunno....I'll debug if have time...
