Electrified brig floor

[Sundance]

What ways would you suggest, then? Prison breaks are great, but they shouldn't be able to be conducted in plain view.

I don't want to derail your thread, but I suggested a while ago that the brig needs to be:
A) More fortified, more than just one window to escape (i.e: disposal)
B) More orientated. Have a way that the prisoner CAN get back his stuff
C) More personal. The big open prison was meant to be that you could interact with other prisoners, but this isn't the case. Smaller, 2 man prisons would be a better approach.

Here's a mash-up of what I suggested:
