"The Sketch" 

Meaning:
 What defines the depth and what takes it away again? 
 Escher often left the plane ground by his mathematical 
 way to create illustrations. But it's also really funny 
 to do exactly the left way: creating something organic, 
 which is ment to be rendered by purest maths, and completing 
 it by drawing a completely free illustration as a TEXTURE 
 without any calculation, to let be rendered together...that's 
 nearly the opposite of what Escher did, but it comes out in a 
 quite similar way...=} ...even if it is not that amazing... =I
 
 Another funny thing...this time again...is that I didn't 
 even touch it with Photoshop after it had been rendered. 
 This is Lightwaves clear and unretouched result. The drawing 
 is a frontprojection image, which I had drawn with Photoshop...
 all together tooks almost a whole Friday, and the most 
 complicated thing had been the lighting. I attempted to let 
 the drawn parts be identifiable, so I had to find a way to 
 show the beginning of the plane ground by taking care for a 
 well enough appeariance...it's really been not too easy to 
 me, so I'm still not too sure, but it's been a pleasure at 
 all, so I don't regret anything...=)
