Qubits as an art tool

Qubits placed in a open waveguide may play a role of mirror for microwave radiation. These are not standard mirrors though as the reflectivity is frequency and power dependent. If there are more than one qubit in a waveguide these properties may give rise interesting effects (for the first experiments with two qubit in a waveguide see this paper). But else they can be good for? Following the idea of Arjan van Loo we can use qubits for drawing pictures!
