Tomorrow (or this evening if you're in Australia/New Zealand) is your last chance to see the Transit of Venus: I can say this with authority unless you intend living another 105.5 years.
The last time Venus passed in front of the sun was on June 8th 2004. We were living in London and I used a pair of binoculars, a piece of cardboard and a camera to record the event (a guide to using this method is here).
So don't miss it - it really is the last chance to see. Just don't look at it directly or it will be the last thing you ever see.
