'Vortex Tool' & 'Physics Manipulation Tool' concepts, UI & game design proposals created for an unreleased first-person game developed in 2014. I envisioned this player-held tool to be a cross between a chainsaw and a power-tool. You would use the tool's energy to envelop large objects and lift them; wrestling with the tool as it fights to keep the object levitated.
