Tobias Kipp and Timo Pitkämö have taken the art of pyrography into the streets.
The two German artists practice street portraiture with an unusual twist. Swapping a pencil or paintbrush for a sparkler, they draw portraits with fire in the amount of time it takes the sparkler to burn (84 seconds).
Check out Environmental Graffiti's interview with the creative duo.
