Maybe some line lasers are made like that (now that you mention it I do recall seeing tripod mounted lasers which are probably spinning POV things), but I’ve got a bunch of line and cross laser modules which 100% do not have moving parts. I’m not sure why I think this, but I understand they’re made by just putting a glass cylinder in front of the laser diode module, working as a kind of 2D lens... Pretty sure that’s what you get in jigsaws and circular saws as well?
