A chap going by the name of sirleechalot has created a BioShock case mod which subverts all natural laws of RPG elemental attacks. How did he achieve this alchemical affront to all we hold dear? With five gallons of horse laxative.
Mineral oil is funny stuff. A by-product of petroleum distillation, it looks like water, acts like water, but crucially in matters of avant garde PC construction, is non-conductive. It also has noteable laxative effects when consumed, and so is used by vets to hollow out horses.
As a result of these properties (less so its equine flushing functionality) it's the perfect stuff to use in a submerged BioShock case mod. Which is exactly what has happened here. And while the sight of raw computer innards and the steampunk design of a Big Daddy is a little bit of an aesthetic juxtaposition, I think it looks rather natty. So full marks for sirleechalot.
And he gets big bonus points for using Bobby Darin on the video soundtrack, naturally.
