I'm not the type of person to ad applications on Facebook, but there was one drawing tool released several years ago, called Graffiti, for which I was willing to make an exception. It is a very basic tool - the only variables are colour palette, brush size and opacity - but there is a certain zen-like quality in its simplicity. It quickly attracted thousands of other users, who began pushing the limits with stunning photo-realistic drawings. It has actually spawned a sizable community of artists who share their art in online galleries, and art contests sponsored by big-name companies. I recently entered a Graffiti contest called Future and Technology, and won first prize in the Architecture category with the above abstract sketch.
Rod Skimmins, DJ of the monthly Bang the Party at the Boat in Kensington Market came across my Graffiti work in an online public gallery, and asked me to illustrate a portrait of Grace Jones for his upcoming album. The illustration was incorporated into the album cover design as you can see in this picture.
