Blobs

While playing around with functions and graphng, I found an equation for a blob which takes the shape of any function. It is simply the equation for a circle, but modified slightly.

For a blob that takes the shape of a function

, use the equation

where

varies.

Try it out with a graphing calculator capable of using sliders for

, or use a CAS.

For example, you could examine a blob that warps its shape around the curve

by plotting

with

and varrying

.

You can also use it to make a heart around

by plotting

.

Re: Blobs

A similar example - but this time made with a warped ellipse, rather than a warped circle, in the shape of the sine function. It resembles a snake!
