We may also see the term adopted in (altering loading animations) and architecture (kinetic facades that modify their swaying response to wind).

However, based on phonetic and linguistic decomposition, I can offer a plausible interpretation and then provide a around the most likely intended concept.

If "alter" refers to car modifications (as in "altering" a vehicle), there is a large community focused on building custom cars and creating automotive-themed media to build a brand or generate income.
