Render 3D surfaces from mathematical expressions

Enter a mathematical function and have it rendered in a 3D space.

-----

Equations are entered as a function of x and y. An example for a unit sphere would be:

f(x,y) = (1 - x^2 - y^2) ^ (1/2)

Nice!

But try to use input with type="number" (WebForms 2) http://www.whatwg.org/specs/web-forms/current-work/#extensions
Also use labels for input fields.

Brilliant... this especially shows the potential of <canvas>. I can imagine an educational website, that teaches children about various functions, with immediate output on their screen.
