I enjoyed it indeed! Conclusions? The oscilloscope doesn't tell the whole story. Some waves might look very different but sound same, while other waves look very similar and sound different.
How about sound examples? Ok, these waves would all sound the same anyway, but many people would not believe that until they heard it.

However, I can't resist and do a little nitpicking. You write: "(omega) is the frequency in Radians". Omega is the angular velocity (the frequency times 2*pi), and is measured in Radians per second. The product omega*t is measured in Radians.

I still remember when I was in physics class, 16 years old, and couldn't get my head around angular velocity when there was just something oscillating and nothing was rotating at all...
