LaTeX Equation Editor

FrogPad

I'm sorry if this post is in the improper forum category. I absolutely love the simplicity of the forums inline latex for the generation of mathematical expression. I've been searching for something that would accomplish the same thing. However, unless I do something custom my options come down to: mathematica (I already own maple, so I don't want to spend the money on it), publicon (it looks amazing... but I just want to TYPE in latex), or use the some available libraries and write my own implementation. I would do the latter if time was on my side, but unfortunately I am to busy for this. Then, as luck has it... I cam across this:

This is exactly what I am looking for. But, I don't own a mac :(
Therefore, I was wondering if anybody knows of any clones to this software.

1000 thanks,
