Fixing Led Zeppelin with Autotune | Adam Neely (video, 17 min) – It’s common to hate on autotune, but at least some of the people who hate it are just thinking of that robotic voice effect, which is not really what autotune is. This video applies autotuning to some classic songs, so that you can hear what it really sounds like. The effect is fairly subtle, but you would be justified in complaining that it flattens out some of the expressiveness of the voice. At the same time, I’m sure some listeners won’t be able to hear the difference at all, and they would be justified in being completely apathetic about it.
There are 48 regular polyhedra | Jan Misali (video, 29 min) – I’m interested in geometric oddities like this, because they’re artistic inspirations. That said, I feel like he plays pretty fast and loose with the definitions and assumptions here. Once he starts talking about regular apeirogons (which have infinite number of edges), it’s unclear what exactly distinguishes a regular apeirogon from a non-regular apeirogon. (Wikipedia’s definition, “a partition of the hyperbolic line H1 (instead of the Euclidean line) into segments of length 2λ” is not too helpful either.)
I’m also wondering what’s to stop you from constructing a “regular polyhedron” consisting of an infinite number of heptagons densely packed into a sphere. Well, you can’t make origami of it, so there’s that.
