I was reminded of these creative escalator ads after reading Zee’s post on Awesome 3D Street Arts. It would be awesome to see some these 3D arts on the street. It even becomes brilliant when companies use these 3D arts to advertise their own company. Please go to the following link view the 15 Great Escalator & Stair Ambient Ads: http://www.creativeguerrillamarketing.com/guerrilla-marketing/stupendous-steps-15-great-escalator-stair-ambient-ads/.
Here is a video showing the escalator ad for hair saloon in movement. 
I also like this Pizza Kingdom one showing the cheese got stretched on separating pizza slides when the escalator moves.
