When you Touhou-ize your engineering term projects.
Last semester, I was working on a galvanic skin response detector composed of a couple of finger-encircling electrodes connected via a simple analog filter block to an Arduino, which sent data via USB to MATLAB for plotting. In order to determine the system's efficacy, I needed a reliable way to make my hands sweat, so I loaded up LLS on lunatic difficulty. As predicted, I got nervous, so the data was perfect, and you could even see spikes in the graph when I got hit.
I then proceeded to present my results to the class, complete with screenshots, and my professor seemed pleased. Got an A on the project.
