Hi! I'm new to crafting with cardboard, and I've been wanting to upgrade my art stall with some moving signages :D I'm trying to look for a tutorial for a sort of waving hand mechanism, but I'm having a difficult time doing so. Is there a specific name for a back and forth mechanism? And can I ask if it's possible to rig it to something battery powered? Thank you in advanced for any advice 😄
