Boris Tellegen, aka Delta, is a visual artist who works primarily in the field of graffiti painting. He studied Industrial Design Engineering and emerged with a unique painting style: his abstract lettering resembles isometric plans for high-tech vehicles or architecture from the future.
Not exactly graphic design (although he does do the odd record sleeve), nonetheless, his work is visually stunning.
On a different note, if anyone can identify this cracking DnB tune, feel free to drop me a line.
