create implication stop_motion -> unconventional_media
By definition it's a form of unconventional media as it's animation created with action figures/model kits/clay as opposed to being drawn.
Tangentially related, I was going to implicate a few other forms of unconventional media as well (namely food art and latte art), but it turns out those tags are used for both the unconventional media forms and art that depicts them in drawings. Should we make separate medium tags for the unconventional media forms specifically?
