Dear All

I saw a water feature on a programme last year but I've forgotten what it's
called. It's birthday time and I've been promised one if I can remember
what it's called and where you get it. Thing is, the internet search
engines are not much help when all you've got is a description - not quite
human yet!!! That's where you guys come in...

This thing is like a stepped flow of bowls and when the water goes into the
next kidney shaped level it gets all oxygenated before flowing into the next
level. It's a very ergonomic thing. It's got some sort of name and the
annoying thing is that I easily found the sites when the name was fresh in
my mind last year but... ahhh memory fails me and I didn't save a link. The
word bioform seems to be ringing bells but it's obviously *not* that cos I
think that's a bra!

Can anyone shine any light?

TIA
