Thus far my professional career has revolved around simulations - specifically, a simulation called VBS, or Virtual Battle Space. If you at all follow the military simulations world or are a big fan of modding the ARMA series, you've probably heard of it at some point. You can read more about VBS and the work I've done for it by clicking here or the image below.
In addition I've done some minor student work researching and creating my own pen and paper simulation, meant to teach team building in a group. While less technically impressive, it's available for viewing here.
