If photons had a nonvanishing mass, the electromagnetic fields would show different characteristics than those we are used to: a wavelength dependence of the speed of light, modifications of Coulomb's and Ampères law and thus different fields for charges and dipoles and so on.

Computer games look extremely pretty these days. Find out how a decent understanding of physics makes it possible to implement 'realistic' computer games!
