I have that model ... Bob Dawson and I built it together while we were at Cambridge. Probably I should contact him.
I was expecting to see the photos, but the jpg are linked there instead of visible. IIRC you were using a self-made CMS for your blog, with more support for math formulas. Does it not allow images?
Everyone complains about how crap my website is, so in this case I've just exported a page from my internal zim-wiki. Yes, it can have photos, but it doesn't give any control over sizing or positioning, so I'm providing links for people to click through to.
It's the middle of my working day and I'm in the middle of meetings, so I don't have time to do anything more right now.
Interesting ... and baffling. I've simply exported that from the zim wiki, not doing anything special, so I have no idea why the internet archive would complain about it.
