1. A system for compressing a second graphical data that occurs in a sequence of graphical data after a first graphical data, comprising: a processor; and a memory communicatively coupled to the processor when the system is operational, the memory bearing processor-executable instructions that, upon execution by the processor, cause the system at least to: transform the first graphical data from a first representation to a second representation to produce a transformed first graphical data; transform the second graphical data from a first representation to a second representation to produce a transformed second graphical data; determine a difference between the transformed second graphical data and the transformed first graphical data; and transmit the representation of the delta to a computer across a communications network.
