I like making video items. Though I admit that I like editing and directing rather than the camera and sound stuff. Everything I made so far is targeted at specific audiences and way too boring (or too private) for Youtube.
I love acting and directing. I used to direct a theatre choir until 2004. Biggest production was the Opera Carmen in 2003. Since then my daughters require my attention and my theatre ambitions have been shelved.
I love coaching the field hockey team of my youngest daughter with Kampong. I am addicted to gadgets and the Internet.
