Love doing this one

Have done it about 2 times so far. It's great exercise to do, it seems to be like a direct experience of geometry. Sense of perception was shifted quite a lot. Got intuition into dimensions etc Still hard to formulate in words what it is that has been experienced.

I haven't done this one yet. The visualization seems quite complex to me. For some reason I am quite intimidated by it. I loved geometry in school, but feel stressed when I think about this one. I am going to record it as well, to help me with the visualization, but even reading it without visualizing is a little difficult.

Yeah, this one took me a few tries to get. When I could do it, it gave some very interesting insights, more on a 'gut' level rather than 'head' level.
