Brains

From Simreal

---

Back in 2004 I made a shell mold around an anatomical brain model (see BodyParts) and then I cast a couple of brains in that mold. I never liked the mold -- it curled! What cheek! And the brains were only decent. I wanted something slightly bigger and with a better mold.

So this year I sculpted a brain pretty much from scratch and cast a large, expensive block mold out of urethane around it, which in turn was encased in a hydrostone mother mold. Hefty stuff, but should last ages.

Here are a few pics of the resulting brain. One of my air sprews got clogged, and my silicon pour was a bit bubbly, so it's not perfect... I was in a hurry! I'll make better brains later.

The silicon itself is EcoFlex-010 from Smooth-On, which is amazing, soft, squishy, disturbing stuff. As squishy as this was, real brains are far squishier... more like Jello I hear (though formalin toughens them up nicely).

Sorry about the bad focus on some of these... it was dark.

Here's one of the old brains	New Brain!	The red wiggly bits were pretty much a quickie to give it character	Old and New, side by side.
