If you have a 3D tv you might want to tune in to BBC HD tonight where you'll be treated to over three hours of the opening ceremony of the Olympics in side by side 3D starting at ten to nine this evening (27th July).
Every night at eleven, through out the Olympics, there will also be a recorded 3D highlights show for one hour every day with the mens 100 metres final at half past eight (through to ten pm) on August fifth, and the closing ceremony (nine pm to twelve thirty am) on August twelfth being broadcast live.
At the start of each evenings coverage you might be interested to see the sixty second films of atheletes in action, filmed with a phantom camera, which Kim Shillinglaw (head of 3D at the BBC) promises to be breath taking.
For those who don't have a 3D tv but are thinking of getting one, the 3D broadcasts are unecrypted and completely free so you might want to record them and play them back at a later date. There are a variety of 3D televisions out there but for the highest definition you will need the type that use active shutter glasses as the other type, commonly known as passive 3D, halves the resolution.
I won't wade in to the "active 3D versus passive 3D" debate here, each have their merits, my own 3D set uses active shutter glasses and is definitely a good option but it's really down to personal choice.
