There's an old adage about relationships - if you're able to keep a plant alive, you can get a cat, and if you manage to keep that from starvation, then you're ready for a long-term relationship.

Well here's a way of cheating at stage one.

The "Practice Plant" is a concept from designer QianJun Gao.

It features three "flowers" which display barometric readings and turn different colours depending on status, namely whether you've managed to keep it blooming.

The surrounding leaves will droop if the "plant" needs attention.

(But there's also a restart button if your green fingers turn out not to be so green after all.)
