Stars as communication devices

I've been thinking about the use of Dyson Spheres as a long range communication device. The sphere would effectively have an and open and closed state for a collection of panels which could be swapped in rapid succession.

What I'm thinking is that with a setup like this it could be used to transmit binary information at the speed of light in an omnidirectional fashion. I'm thinking from a fixed point of view this would look a lot like a pulsar.
