All the Blackheath fireworks videos I’ve been able to find are wobbly. I spend quite a lot of time each year looking through them, because I’ve never managed to go to the event itself! I couldn’t find any professionally shot clips on YouTube. Even Lewisham council’s preview trailer is wobbly.
So, if you’ve got to have wobbly, at least you can have wobbly in 3D. Hit play, then click on the 3D button to change the viewing method. If you haven’t got any red-cyan glasses, then your best bet is to set it to “side by side”, don’t watch in full screen mode, and cross your eyes a bit. Avatar it ain’t, but it’s still quite neat.
