Riley Walz scraped over 100 million drawings and paintings from Artsonia, an online gallery of student art, and made the lot searchable: type anything and you get a trend line from 2005 to now plus a grid of the actual drawings, each dated. Pikachu peaks twice, in 2017 and 2020; Baby Yoda is a single spike; Martin Luther King Jr. bumps every January like clockwork. It is Google Trends for the crayon economy, and the source material is unimprovable.
