I've recently worked with Plymouth Museum on a mural for their surfing exhibition with Paolo Fiore and Joe Lyward. It was based on the 'Under the Wave of Kanagawa' by Hokusai with some illustartive modifications.
It took us 3 long days to finish it...
and a cherry picker to reach the crest of the wave
The finished piece!
Paolo designed some funky jelly fish pattern and the surfers
and I designed the crest of the wave as dolphins
