It now seems that the vision he saw was actually work in progress by Dean Kenning for his exhibition 'The Dulwich Horror- H.P. Lovecraft and the Crisis in British Housing'
The window exhibition runs at Space Station 65 in Northcross Road, East Dulwich until September 2nd, with the launch this Friday 27th July, 6.30-8.30 2007 and a closing event with performances on Sept 2nd 2007 (all welcome to both events).
According to the blurb 'The outside walls of rented accommodation constitute a vast advertising billboard for Estate Agents. They appear without warning. ‘TO LET’, ‘LET BY’ - they never seem to come down. If you live in rented accommodation, your home has been branded: you are a temporary occupant subject to the authority of the property owner and his agent. For The Dulwich Horror ‘TO LET’ signs across London will form the canvas onto which Dean Kenning will paint images representing the supernatural and monstrous entities from H.P.Lovecraft’s Cthulhu Mythos. Horrible alien beings such as Yog Sothoth, The Outer Ones, and Great Cthulhu himself are famously beyond description (the sight of such creatures would drive any human over the edge of insanity). Nevertheless, Kenning will have a go'.
Sounds great, but must admit my favourite remains the lego Cthulhu.
