Ive have read about Takashi's tank before, Its awesome. We would all love a small chuck of nature like that in our living room.
Yes I have been meaning to put glass panels into the side of the pond, havn't added that part yet, Im still working on it. I realise its not realistic in NZ but could still be possible if/when i have the money.
I'm using Archicad. I use it everyday at work.
