FooPlot

I was just browsing Simple Spark and I came across a lot of neat software that I'd already used, some ok stuff, some interesting stuff and only (so far) one app that really stood out as uniquely awesome.

FooPlot is an exceedingly simple webapp that does it's job fantastically. It graphs. That's it.

It does what you'd expect from a TI-83 or such-like. It graphs functions, finds roots and intersections and not much else. IT also has some 3d stuff that makes you think 89. If you want to see all the functions it can handle look at the help tab.

The coolest thing is that you can tell it what to graph via URL. Check it out:

fooplot.com/3x+5
fooplot.com/e^x
fooplot.com/tanh(x)/((sin(x))^2)
fooplot.com/floor(2*sin(x))

Fabulous.
