I took a chalk stick and started to draw on a blackboard. I set up lights and a camera. 12 pictures would make a second. After 5 years came out my first movie, The Atomic Carrousel. It taught me to recreate movement through animation.
Thanks to technology, I now have swapped my good oldschool blackboard for a graphic tablet. I still draw every images with my hand, but now I can easily mix them with movie camera images (cf trailer "the last eye" or "when art explains technology").
The way I work might take time, but it allows complete freedom. I believe imperfection brings an unexpected touch that distinguishes my work from animation software's productions.
