Story from back in college..

It was the golden days of Flash Facebook applications. I have developed a very simple Rubik's cube solver in Acton Script 3. I was testing it out at the back seat of the class during the first day of Advanced OOP in Java module.
Our lecturer was going on and on about how awesome Java was and what all you can do with it. After a while he said "do you know this thing called Rubik's cube?" **explains what it is for a while** "Some people have even made software to solve Rubik's cube with Java. Can you make something like that?"

I was like "you mean like this one?" Pointing to the app on my laptop.
