Falling Sand Game
Everyone needs a “break” at work and there are a ton of different games online worth checking out that will play on any system regardless of specs. This is one of my favorites from back in the day. It kind of reminds me of Zen garden, but here you can play around with different types of “sand”. You can build walls and pour in water, oil, set it on fire and just waste the day away. Just don’t let your boss catch you.

This requires Java.
