Bayleaf is a beautiful house at the excellent Weald and Downland museum. This is something like the Bayleaf timber structure (from memory) but without all the textures. Because of the 64 bit Director Shockwave problem I've used Wirefusion which requires Java. This model is only a proof of concept and will be checked for accuracy and have textures added in the near future, but it does give a basic idea of the main parts of the timber frame and, with a bit of imagination, what the final interaction might look like. 

Bayleaf itself is well worth visiting. The staff and volunteers at the museum are immensely knowledgeable and often they make sure there is someone with expert knowledge in the larger houses who is more than happy to chat to anyone passing through.

Have to say, WireFusion seems to be winning hands down over Shockwave on the web based 3d front. The only disadvantage I've come across is that the models and textures have to be fairly small or the model just freezes.
