This is pretty cool ...

Brookstone has these crazy ecospheres that came about as a result of some NASA experiment. The life expectancy of the ecosphere is about 2 years but it's not unheard of for them to survive up to 10 years. Can you imagine having this glass ball of a world for 10 years?! I mean I am having thoughts of having the betta for 2-5...

Brookstone says this about the ecosphere:

The delicate coexistence of animal and plant life (red shrimp, algae and microbes) thrives within each glass sphere of seawater. This technology was developed by NASA scientists as part of a growing initiative to study our planet’s biosphere.

The pictured ecosphere is 4" and costs $65 plus an extra $12 shipping surcharge. They have other shapes and sizes as well. The largest costs $500 plus the surcharge.

I personally think Nick would love this if he got it as a gift. The wheels in my head are spinning ... what about gifts for the groomsmen? Knowing Nick's groomsmen, I am pretty sure they'd think this ecosphere to be a pretty kick arse thing.
