Ever wondered what it's like to fly around inside a digital camera? OK maybe not, but in case the question catches your interest here's a video made by engineers at X-Tek (now owned by Metris), using the same 3D X-ray technology that they used to image the Antikythera mechanism in 2005. Andrew Ramsey of X-Tek showed me this fly-through on his laptop when we were in Oxford for a conference on the Antikythera mechanism last month and I found it quite mesmerising, like being transplanted into an alien world of giant floating springs and screws. This youtube version is a bit fuzzier but it's still a fascinating (and technically impressive) insight into what really goes on inside your camera. Andrew has posted a second video too, which flies around inside a lizard skull.
By the way I won't be posting again for a while as I'm off to India for a few weeks. I'll be travelling with my friend Gaia Vince, a science journalist who is documenting the effects of climate change on the planet - you can keep up with our progress at her wonderful blog, www.wanderinggaia.com.
