From the Intergovernmental Oceanographic Commission, a gif animation of how the tsunami derived from the earthquake and how it spread across the Indian Ocean.
I've read a few comments on various sites about Burma, a country known for its repressive and dictatorial military regime. By their accounts they have only been lightly hit, although whether that's the truth or just an excuse to keep foreign eyes off them is anyone's guess. It's interesting to see that the most intense force of the waves was where you would expect; Indonesia, Thailand and Sri Lanka. It's also interesting to see the strength of the waves that missed that area completely and eventually struck East Africa.
