Every writer has a different way of doing this. The really legendary ones seem to turn to drinking, to drugging, or to chasing down a mid-life crisis in the guise of a string of women half their age. Me, I'm not the stuff of legend- I like to play with toys.
Previously, I've mentioned my, uh, son's (yes, that's it) Planet of the Apes Kubricks and the Monkey King Playmobils that I've customized. Believe me, I could go on and on about cool toys I have in the house, cool toys I've had, or cool toys I want (I'm on toy probation, in general. One in, one out is the house rule) but this isn't a toy blog, it's a writing blog, and in that vein, I won't mention my wonderful double barrel soft dart shotgun (oops). Instead, I present for your enjoyment, Michael Moorcock's Elric of Melnibone (I've been reading Mervyn Peake's Titus Groan and it's given me Moorcock on the brain. Heh.) It's a Playmobil custom, done after Brom's well known painting:
The best part is that my son can play with it, though I've decided not to teach him the part about black swords and their soul-stealing properties. Maybe when he's four.
