UK based Addirect equips washrooms of bars and nightclubs with the AddMirror, displaying backlit ads.

Addirect already signed up over 150 Bars and Clubs in London that run ambient advertising with the Addmirror.

The AddMirror reveals up to six A4-sized advertisements using pre-set lighting sequences.

So while picking your nose, you now get exposed to advertising directly in your face. Addirect was founded in 2003 by entrepreneur Ben Grant.
Addirect wants to expand internationally now after their success in the UK.
