Petrolhead, your matchstick art is awesome! Well done!
As to my hobbies, when I have spare cash, I like to get up and fly. Got my private pilot's licence in 2004 and have just under 200 hours up incl. my night endorsement, high performance and complex aircraft endorsements, too.
A friend of mine owns a Victa Airtourer which is an ex-Singapore Air Force aerobatic trainer. I go flying with him about every 6 weeks. Last time we went up, I piloted 4 x 4G vertical loops over Westernport Bay. That was cool!
