Counterlight
Two lights. One direction.
The blue circle follows your input; the amber diamond slides the opposite way. Both keep moving until they meet a wall. Bring them onto their matching outlines at the same time.
A wall can hold one light still while the other finds its way. Take a detour, cross paths, and bring them home together.
