Rhizotron originally means "clear-walled chamber through which one can observe roots as they grow". This version is a little different as it climbs through and over the tree tops at Kew Gardens.
I was impressed by how it seemed to fit into it's surroundings. It would have been an obvious (aesthetic) choice to make it from wood but I prefer it in metal (iron?). It looks stronger for a start. I know wood can be as strong as metal, but I can imagine that those of a vertigo disposition would feel better knowing it was made from metal. The rust colour looks organic and even bolts have a natural feel about them.
I loved the way they've mirrored the look of tree branches for these supports. It's got that nice exciting engineering Brunel look about it. It doesn't look threatening. It looks cool.
The view are pretty cool too and you get to walk amoungst the trees. Little plaques tell more about the trees as you pass and there's even a Bluetooth game.
Actually the Kew website is pretty good and there is a good interactive map of all the trees. Exactly the sort of thing Kew should be doing. Good.
All good fun. At the moment it's a temporary structure but I hope they make it permanent. More pictures on Flickr.
I liked this as well. Reasonable, common sense, non preaching, on brand message, environmentalism. One last full stop wouldn't hurt though.
