I don't know about all this nonsense but I got my boss spherical ice cubes + glasses they look neat and make you look neat and that's about all that matters to me (someone who likes to look neat). She sent me photos last night and loves them. :)
Personally, I have my square king ice cubes (as well as just about everyone who got an xmas gift from me this year) and I love them. The only problem is that all my regular drinking glasses are too small, save for my coffee mugs. The classiness is infinitely diminished when drinking rye from a coffee mug.
So, cooling or no cooling, math or no math, big square ice cubes and spherical ice cubes just look fucking neat.
