Fractals, mandalas, endless rabbit holes you just keep falling and falling further into. These things have fascinated humans for an incredibly long time. The amount of time you can spend, just staring and noticing, is equal to the possibilities, these constructions offer. Basically endless.
Hang one of these on your wall and watch as visiting friends and family members lose themselves in the art, just as you did so many times already. Just yellow, white and grey, creating a suction that pulls you in and never lets you go completely.
