here a paint i did depicting a Demon of Logick --
i tried keeping it away from traditional demons and add a rather impersonal feel to it. The surrounding is in fact a representation of the Space of Thought, in which the Demon of Logick is trapped, together with his companions Calculus, Dedux, Ordinatus and Modus. (The last two are not in the picture ) These are the incubi of Calculation, Deduction, Order, and Measure.
I used Painter 9 nd PS CS for the pic.
Tell me what you think!
