When Rob decided to try to control smoke - an idea he first toyed with in 2007 - he realised he needed to channel it, while still letting it do what it did naturally.
To him, this sounded like animal training - and for that reason, he created images such as dancing horses and zebras. And in the series, called Smoke Rings, the performing animals - taken out of their natural habitat and trained to jump through hoops or balance on platforms - appear almost ghost-like, their wildness tamed
Given the dangers of creating his work, Rob wears fire-retardant clothing, with a carbon filter unit and fresh air system with full facial mask. He originally set up his studio in a metal garage. More recently, he had a special room built adjacent to his house to keep all his artistic endeavours isolated.
