I've just been reading through the forums about terrariums (I'm looking to make one) and you can even use a 2L bottle as one
. It'll work for small plants, just chop off the bottom and allow aeration by cutting a few shapes out of the newly cut plastic (be careful though) and keep the bottle cap off. Spiffy! You do have to be careful with mould though.
I've been growing carnivorous plants a similar time frame as you heh. You learn so much so quickly thanks to these forums!
I'm afraid I'm not too good with drosera, here's hoping someone with experience can help you.
As for good looking plants -- Pinguicula are my favourites. They look like flowers that are constantly in bloom (despite having very simple yet stunning flowers of their own) and have a very similar trapping mechanism to that of a drosera; they exude a buttery substance from their leaves. Pinguicula are also known as Butterworts so you know where it gets its name.
I personally think Mexican varieties are easier to care for, you can find the caresheet for them
here if you want to have a look. Mexican Pinguicula do have a dormancy period, but it's completely different to that of a venus fly trap -- I find it easier to replicate.
Utricularia (bladderworts) are nice to look at, they flower profusely and are generally happy as long as they are kept damp. If you're interested in them, I suggest Terrestrial Utricularia, I made a care sheet on them that is available
here.
