Mc Escher is an extremely unique artist. its unlikely there would be any artists that can imitate his style. If you Google 'MC Escher Lego' you can view a piece of art that a bloke did of Escher's 'Relativity' made entirely out of Lego bricks. its pretty awesome.
Escher's drawings are considered timeless because they include mathematics and architecture in the style of art. They are also difficult to date because they rarely depict human forms.
