My avatar was an obvious and mandatory choice, given the existing choice of my username, as explained in this related answer. However, in pracitice it wasn't too easy to find a nice picture of TARS that I'd be satisfied with. This is also the reason why the actual execution of my idea to use this username was even delayed from its initial inception towards the day I got myself the BluRay of Interstellar and was able to capture a nice picture myself.
But even the manual capture of TARS in a fitting surroundings and a pose that emphasisizes his unique and simplistic structural form wasn't as easy as I might have expected. So I settled on a compromise, fueled by a little enlightenment: Why am I so eager to highlight his full body when avatars on these sites are usually rather face-based, especially due to the limited size of the final picture in its everyday use?
So with this insight and my incapability of finding a fitting full-body image, I just settled for a picture of TARS' "face", which is, like his whole body, deliberately non-human and pragmatically functional. And to lighten the mood as well as highlight his nevertheless unique persona, I of course chose a portrait with the joking cue light on.
