Same here! I am still utterly fascinated by the concept - and I wish we could really test for these maths to see of there is more validity behind it. I love trying to visualize what higher dimensions might look like -- the way space bends on itself is so cool! I can't say I've tried doing that exactly, but I have messed around with making some 3d fractals at least!

Discipline was written by Paco Ahlgren. I believe it's the only novel he has written and I don't think it had tons of sales, but I met him totally unplanned when I took a visit to Barnes and Noble as a young teenager. He said some things that really resonated with me as a kid that, if I'm being totally honest, had a profound impact on the way my life played out. I don't think I have read Flatland, but I've heard it mentioned before! I will definitely see if I can snag a copy next time I'm at the local library.
