I was trying to think what Bob's Gazebo car conversion reminded me of - this morning I realised that there is something very "Emetty" about it - probably the height to length ratio. This is no criticism - I'm a longtime fan of Rowland Emett who drew all sorts of fantastical whimsical things, but excelled in his railway items. For those who don't know, Rowland was a cartoonist and some examlples can be found at

There was, and maybe still is, a model based on his Far Tottering and Oystercreek railway, called the Far Twittering and Oysterperch. One of his locos was an 0-2-0 called Hero. Makes me wonder about an 0-5-0 switcher, with 3 wheels on one side, and two on the other!
His more modern equivalent is Bruce Bates' Birdwater and Raspberry

Gn15 would be a wonderful medium foran exhibition layout (or even a pizza) featuring that sort of thing.
I love those Japanese garden railway cars too- thanks for the links
