Yet another experiment,

Bézier Curves of any degree can be visualized! You can also visualize straight lines, but that's sort of pointless.

Cool - I now understand Bezier Curves better than I ever did before.

...that is, until I did one of order 100. Got real trippy real fast

Pretty psychedelic!

Hah, try doing one with each point going around the canvas in each corner, one in the upper right, upper left, bottom left, bottom right, and repeat that for a lot of points. The visualization looks really cool.

Try a square or pentagon, too! Whoaaa, spinning squares. Relates to geometric sequences in some way. (Haha, because it's very geometric?)

Also try a back-and-forth pattern. (Ex. (-100, -50), (100, -40), (-100, -30), (100, -20), etc. in Cartesian coordinates - very rough, and horizontal/vertical scale won't matter a lot). It's a straight line, except when it's not.

Similarly, try something like (-100, -50), (100, -50), (100, -40), (-100, -40), (-100, -30), (100, -30), etc.

If you think about it, Bézier Curves are just a 2D glorified binomial theorem

The canvas is 1024x512, so the corners are at (0,0), (1024,0), (0,512), and (1024,512).

If you want to consider the center of the canvas as (0,0), then the corners are (-512,-256), (512,-256), (-512,256), & (512,256).
