The idea is good, but the implementation is boring. Pair that tech up with a terrarium, and you've got something. Add sunlight and clouds and you could end up with something fairly artistic.
That it mimics the outside weather is gimmicky and misplaced. That's a sidefeature, a checkbox; thats not what really matters. Something that looks cool that people will buy is.
Hook your terrarium/aquarium up to the weather somewhere interesting (e.g. the amazon, great barrier reef etc) I wonder how fish, turtles, corral etc would react to that? It may help them sync and spawn.
Having the sun (LEDs?) and moon wonder over the sky at approx the correct times, weather and temp all correct. Could be a really neat little project!
