Those fly traps a very cool. there is a lot of art shops in different tourist towns in Arizona that have a lot of hand made glass objects maybe look into trying to sell in a similar shop around your place.
I like the idea of a water pitcher pitcher plant or a set of glasses and pitcher for lemonaide. Might not be a big seller but something that you could offer as a order by order basis.
I would also be interested in a cepholotus if you get around to making one.
