Some of the best ideas are born in the bar and now a group of architects seem to have turned to the bottom of a bottle for inspiration.

Croatian architects Entasis won a competition to design new towers in Zagreb, with an eye-catching design featuring two leaning towers and two straight towers in clusters.

Local stirrers have renamed the 1+1 project the Drunk Towers because they look like drunks leaning on a lamp post.

Perhaps the project was born after a pub session got creative?

The towers will be 145m high and are slated for completion by 2011 if the approval process goes to plan.
