Click flag. Press space a lot! Is there a mistake? Tell me! The piece is Malaguena by Ernesto Lecuona, and yes, it is me playing! It was at school! (It's probably my favorite piece ever :D and I kind of butchered it but you know what --) Credit to a magazine my math teacher gave me (to borrow and read). I was not able to solve this problem without the magazine's explanation. I know how to now though! (and so do you :P) By the way, I used the pythagorean theorem to space the pennies properly (aka to find the height of the equilateral triangles). (C# F G# C# F G# G# B A G# F# E D C# ) x infinity I LOVE Malaguena. I'll probably make a project that plays it... that will take some time: coming soon, 2017 summer!
