[TOMT] Brainrot video I watched as a toddler. Poorly rendered, smoothly rounded colorful shapes scaling into thin air. The end result was a castle. Most likely 2015.

In like 2014-2015 my parents would make me watch brainrot videos for toddlers. One I vividly remember but cannot find is one where 3d squares and triangles, in poorly rendered lighting, would zoom in from nothing, and eventually form a structure. I remember it being a castle, but it could have been something else. The colors of the shapes were always neon, and the models they used were always smoothly rounded.
