I like drosera.
I just finished my lego mini mini bog, and it has one ping and a baby spatulata in it. It is coated in water proof stuff so no water can leak out of it, and it is cool. Here is a pic:

And I don't know if there are any toxins, but I doubt it because these are sold to a lot of kids. And the paint? Hmmm... I don't think the plants are coming into contact with the paint, because the baby spatulata has tiny roots and the ping almost nonexistent ones. But I'll have to look into that....Did you wrap the whole thing in like shrinkwrap or something? It looks like it's all sealed somehow.

Cool Idea. I was thinking about using legos or something similar as a potting media to help add air to a potting mix.
