This icon seems to follow me wherever I go. I use it on most social media, for example. I actually drew this specifically for the process of converting it to pixel art around the first time I played Armored Core 1 for Playstation. That game features customizable emblems for the side of your mech and I thought it would be cool to put myself in the game, as it were.
I also made a 32x32 version for conversion to Mario Kart DS. It doesn't look great, and it looks even worse in the limited color range of the MKDS emblem system. This website's tab icon is an automatically generated 16x16 version built in to the .ico file I made.
