"These doodles are done using instruments and techniques I have developed over the past 6 years. Before that, like anyone else, I did a lot of scratching with sticks.
As a calligrapher I have a particular interest in African colonial and pre-colonial writing systems, so when I doodle on the beach its often along these lines. The more angular letter styles take their inspiration from Tifinagh, the script of the Tuareg people of North Africa. It is interesting how that, even to this day, the Tifinagh resembles ancient Greek and Phoenician.
The interesting-looking characters in other pieces are usually taken from west African symbols such as the Adinkra symbols of the Akan people of Ghana and the Ivory Coast. They're mostly meaningless doodles - a play with form."
