Walkie Scorchie Death Ray.
This looks like a story right up El Reg's street.
The new "Walkie-Talkie" building in Fenchurch street, is focusing the sun's rays, and has melted body panels on vehicles parked in nearby Eastcheap.
Interestingly, it's happening right besides the junction between Eastcheap and Pudding lane - The site of origin of the Great Fire of London in 1666. That cannot be just coincidence - There's a master plan at work here...
