Pictures: The sticky note window art battle between two buildings in New York
- Published

A creative battle has broken out between two buildings in New York competing to make the best window art displays using only colourful sticky notes.

It started when a mystery "HI" appeared on the window of a building and the company opposite responded to it with notes saying "SUP".

Since then, creative window art featuring the likes of Angry Birds characters have appeared.

Even some Adele-inspired song lyrics made their way on to the windows.

This window has taken on an under the sea theme with fish, octopus and seaweed.

We reckon this hamburger might make some workers hungry!

A woman puts the finishing touches on this rainbow window display.

Some of the windows have take on a superhero theme, including this Superman logo...

...and Spiderman!

The art battle has even inspired offices in different cities such as Toronto, London and Dublin.
