So yeah, to detract from the seriousness floating all around, I thought I'd post this little gem.
http://www.kaleidoscopereef.com/It's called Save Kaleidoscope Reef, a game where you rebuild a devastated reef after a garbage barge crashes into it by putting polyps all over the place and feeding them plankton until they grow into maturity.
In my own personal opinion, it's a really fun way to burn some extra time, as well as educate the youngin's about our reefs.
Interestingly enough, the devoloper, TrickySheep, is based in New Zealand, and has released a number of other games with an environmental theme, such as Anika's Odyssey, which is inspired by the scenery of Aotearoa, New Zealand.
But yeah, check it out, it's really fun.
