This version of CureStudio (*1) was created for the pixiv Festival. It is a virtual space where people can use paint to draw in real time over the walls and surfaces.
*1: CureStudio lets people experience, in real time, a virtual world from an anime or game, where they get to be a character of their choosing, and dance, pose, repeat catchphrases, or otherwise have fun, all of which they can record a video of.
