"Oh no, why is he upside down?" 

Having been criticized many times for not making enough accommodations for mobile users in web app development, the image is intentionally rotated so that only mobile users can view it normally by turning their phones upside-down. Vola, a specially accommodated design. 

Aside from over a decade's experience in traditional/academicism art such as charcoal and oil, Amarth specializes in computer graphics, game/app development, and optical imaging technology, including A/V production and optical design. He has helped developing web/iOS apps for the Ohio State University online education and has worked as a cinematographer/1st AC for university media production, also functioned as tech support for students and faculties. If you come to the Ohio State University in 2023 or after that as a undergraduate student, then fortunate of him and unfortunate of you, there will be videos he shot that you are required to watch.  

His current research topic is imaging system simulation. Which aims to build a framework that bridge the gap between surface-based rendering models (such as BRDF and BSDF in computer graphics) and the more accurate but cumbersome approach in optical design, allowing the visual effect artists, animators, and compositors to replicate the image characteristics of vintage lenses on certain imaging system without having to know everything about optical physics, computer science, and lens design. 

It has been noticed by many that Amarth has an unhealthy amount of knowledge about death and necromancy, possessing books with strange drawings and incantations, holding flasks and beakers filled with thick red glowy elixir, and mumbling words unknown to be German or spells of the dark art. While he is typically willing and happy to help you solving technical issues with satisfaction almost guaranteed, for your bones, it is recommended to refrain from approaching him for other purposes.
