I live in Western Australia (moved here for the second time in early 2005).

Favorite ideas of my own for wishing it was real because it seems so close: stabilised skates

Favorite ideas of my own for fun: Tarzan's Yoyo, snack launcher

Favorite ideas of my own for cleverness: encrypted compressed air, centrifugal vacuum balloon
