			=====Description=====

	A '''Snail Cam''' ''(aka Drop Cam)'', so-called because of the snail-like appearance, has a slow rise and then a sudden drop. This is a one-event-per-turn cam with a slow build-up to the peak and a rapidly decreasing edge. These cams can rotate in one direction only, which in the case of the illustration shown, is counter-clockwise.
