I'll try and get a pic for you, i'll have to do a bit of tidying, it doesn't look that neat atm.
It is a small 1' 20l cube (one peice of glass curved around with another siliconed to the back) with a small curved flourescent light. I actually got it free with a magazine subscription!
Sand substrate, the second from the bottom eheim aquaball filter, 50w eheim heater (i do like eheim). 1 maramo ball, bunk load of java moss, bunk load of ricca, 1 anubias, 1 crypt, 1 small grassy thing and 1 plant which has yet to be identified because it just spontaneously grew from a bit of leaf that came with the other plants. Used to have the labels but they've long since been lost. I have a small 6" peice of bogwood with ricca and java moss tied down that is actually looking very good. The only maintanence i do with that is every now and again to tie the plants down a bit tighter or they do tend to look a little straggly.
Weekly water change, fertilising with normal hagen liquid feed at recommended dose. Light for 8-12 hours a day, depending on when i turn it on in the morning and go to bed.
Plants get trimmed whenever necessary, but i mostly just let them get on with it.
3 otocinclus and 1 fan shrimp. Used to be the home of a 2" monster fish and a pair of killi's, but these have unfortunatly passed onto the big toilet bowl in the sky. I don't feed them as such, but they get a bit of flake everynow and again, or a drop or two of liquid fry feed for the fan shrimp.
I think it is an absoloute shame that people start w/o live plants, it was always something i would never let people leave the store unless they had some. But, best one can do is educate! That living wall certainly does look interesting.
My mistake as to the trickle filter, i'm thinking of something else! I will admit its been a couple of years since i was last working in the industry and i'm a little rusty on some of the more obscure technical kit. I'll see if i can find a picture of what i'm on about.
Splitting hairs on terminology is fun, there are entire discussion boards dedicated to arguing over the tiniest of things. I wish i could make a career out of fishkeeping. I've gone the otherway, try to get rich enough to buy a fishhouse so there will just be a blurry line between hobby and career
