Sun Microsystems created an online flash game for developers named "the temple of sun" as an attempt to get developers to try Sun studio 11.
The game is pretty much simplistic , you're in a temple similar to those created by the maya civilization but this one was created by developers to protect Sun Studio 11, because the people or their time were just not ready for it. you have to avoid some obstacles, collect some gold and answer C++ questions, and at the final you have to answer a question that can only be answered if you download sun studio and compile some code on it.
Unforunately sun studio doesn't install on my gentoo machine so there goes my chance to win up to $5000.
