It’s one of those days when you really hope things work. A few prayers to the gods of technology later and lots of crossed fingers, and we have Temporary Contact Point on Calton Hill, operating from the boot of a car with a laptop and a wifi hotspot running from a mobile phone.

These photos from the first Beltane 2013 walkthrough rehearsal are not indicative of the amazing pictures that you’ll see later – pictures taken with proper cameras rather than a phone – but as a test of the technology, they’ve done their job. Enjoy!
