Absolutely ideal for night life, bar companies, any light system, or a company which works in colorful entertainment area in big city scale. May be some advertising companies or any demonstration in city scale again.
My inspiration was just a project about cultural meeting point, this never used in there, just remained as sketch.
There is a Escher illusion in logo itself, in every version (colorful, black and white / negative) same illusion happens. It's very easy to adapt any company name in logo because of cool empty space.
Especially name "city illusions" is not common (except ursula le guin's book 1967) so even in musical area this can be concept - name - art of an jazz album...
