what plant is this?

Amano made famous using riccia fluitans as a foreground plant to cover substrate and decor, rather than just a floating plant. On my computer, even enlarged, the pics are too small to see clearly what it is. But I'd say riccia.
 
yeah, i would have guessed riccia too, but even tho its far away, the texture doesn't really look that much like it, but that's probably the best bet. thanks

Is it just me or are those tanks self-supporting (biologically)?

No, you can see the filter intakes on the sides of the aquarium (they're made of glass, so they're hard to see)
 
It's a possiblity that there one of those tanks might be Lileopsos. Pics realy are poor for identifing plants. Amano is known for his work with Riccia but he does use other plants in is Zen presentations.
 
I agree with KoG, it is more than likely riccia. There is strikingly similar tank in Nature Aquarium World Vol.1 (the same one?), that according to Amano's lists, is Riccia. Also, there is what appears to be Dwarf Sag or a similar dwarf, running sword mixed in the carpet as well (the somewhat larger leaf like plants mixed in, particularly noticable in the back left corner).

If you're really interested in this style of tanks, check out the Nature World Aquarium series. They are written and photographed by Mr. Amano and include lists of the plants used in each tank, as well as the specific lighting and CO2 used. I have all three and love em, though the translation into english could use a bit of improvement and there are a few scientific names used for fish which are entirely outdated.
 
More more! Those are awesome pics of Amano's actual gallery... I'd love to see more images of the rooms and tanks in them (seen plenty of Amano's designs, I'd rather see the tank room @ ADA!).
