Processing rocks!

Processing (http://processing.org) is a Java-based graphical programming language. Great for getting instant feedback and making pretty pictures.

IDE

The IDE is the same one that the Arduino project uses. Not a lot of features, but it's quick and works well.

I wrote a simple particle gravity app, and it animates really smoothly. I'm looking forward to using it to make more eye candy!

App is attached as "planets.txt", rename to "planets.pde" for the Processing IDE to pick it up.

C++ Syntax?

I'm a little confused about the syntax of your code here. Perhaps you can explain it to me.

You've got: planets[i] = new Planet(); indicating that planets[i] is a pointer to an object of class Planet.
On the following line, you've got: planets[i].mass = 1. Why does this compile? Shouldn't it be planets[i]->mass = 1?

Processing

Processing is its own language, that happens to look a lot like C++. Kinda like the arduino. Processing is not C++.
