Would you perhaps consider making a compilation of computer screens? I can’t recall how the trolls’ look, and if they spell everything in alternian.
We only really ever see the trolls using Trollian. Their computers all appear to be in English too. The ~ATH file is interesting because it’s Karkat opening it, and the border is grey. I mean the grey could be the default task bar colour or it could correlate to blood.
Basically the troll’s computers just consist of Trollian or coding and it doesn’t give much heads up on how their actual computer desktops look and what applications they use.
