At $45 assembled and $35 for a kit, MechaniCards could quite possibly be the world’s coolest greeting cards. Technically speaking, these creations are “miniature, hand-operated, kinetic sculptures, designed and produced in limited edition by Bradley N. Litwin.” More information. Video after the break.

They are constructed primarily from paperboard, with a few bits of wood, metal, or plastic. They make excellent gifts, and are suitable for mailing, as truly unique greeting cards.
