I think what fundamentally drives my creativity is mixing different media. What happens when you combine text with music or video with spoken voice? What can you add or subtract from an experience to change the feeling? This is what I love to explore through filming and making videos.
When I invested in a new DSLR camera a few years back it came with built-in video recording. Over time this feature grew on me, and I went from recording short clips to try my hand at actually scripting stories and editing. This has resulted in a few rather odd short films.
