  Though some years remain before quantum computation can fully outperform
conventional computation, it already provides resources that can be used for
exploratory purposes in various fields. This includes certain tasks for
procedural generation in computer games, music and art. The so-called `Quantum
Blur' method represents the first step on this journey, providing a simple
proof-of-principle example of how quantum software can be useful in these areas
today. Here we analyse the `Quantum Blur' method and compare it to conventional
blur effects. This investigation was guided by discussions with the most
prominent user of the method, to determine which features were found most
useful. In particular we determine how these features depend on the quantum
phenomena of superposition and entanglement.
