During his childhood and teenage years, Luckey experimented with a variety of complex electronics projects including railguns, Tesla coils, and lasers, with some of these projects resulting in serious injuries.[1] He built a PC gaming "rig" worth tens of thousands of U.S. dollars[8] with an elaborate six-monitor setup.[10] His desire to immerse himself in computer-generated worlds led to an obsession with virtual reality (VR)."
