The Wellcome Trust is a UK charity organization with a penchant for provocative haute design. (They're also the guys that commissioned the awesome raining molten metal sculpture.) Their current window display features two naked human arms. Every few minutes, the arms turn from opaque to translucent, and bright red veins and arteries made of glass neon tubes magically appear. It's supposed to symbolize medical research. Images by Paul Cocksedge Studio Paul Cocksedge Studio main page via DesignBoom
