Perspective lines drawn away from a single viewpoint give the painting the impression of being three-dimensional.
Müller, 40, said that this type of street art had not been around for very long, even though the technique had been used by artists on other surfaces for centuries.
The German explained: "Three-dimensional street painting itself is a very new art form which only a handful of people do worldwide. Its nature is to trick people's eyes and show them a new 'reality'.
"The technique itself is called Anamorphism and has been known since the Middle Ages. It was used by famous painters like Michelangelo, da Vinci and others in their murals."
The work, called Ice Age, was created last August for the port town's Festival of World Cultures.
A video clip that Müller put on YouTube just over a week ago has already received almost 50,000 views.
The artist's previous works include a German high street apparently riven by a lava chasm and a walkway transformed into a rock-strewn waterfall. TheTamshee says: Amazing, how of earth did this German manage to persuade the Irish rain gods to with hold the droplets of frozen crystals, yes rain - that seem to be cascading from the skies every time I visit the Emerald land.
