Should have been in the Rhythm challenge, buddy! Perhaps it was, for a time?
You've given these lights a really creepy anthropomorphic character (I swear the nearest one on the right reminds me of someone I know). The vitalized (Frankenstein) effect is further emphasised by their dispersion and placement; as if they were a herd of dull, grazing cloven creatures ... cows, or maybe wildebeest ... something placid and easily pleased, anyway. And the herd allusion inevitably leads me to an appreciation of your title. Such a lovely game; thanks for the fun and mental exercise, as ever.
