I'm looking for but can't seem to find a utility do essentially do what this (question on Ask Different SE) does, but in Linux.
I like to be able to show people something on my screen without having to enlarge the selection by magnifying the screen/window.
When I used Mac, I had a variety of bash aliases and functions for doing just this with Quicksilver, but now my main machine runs on Arch, where I have not found a similar tool. I'm sure it wouldn't be too difficult to to make a quick Python script for this with some GUI framework, but would rather not duplicate effort if it exists and I simply don't know the right words to search.
I've seen banner, which tries to do similar in the terminal, and tried trawling Google to no avail. Even better would be a utility to display the compiled LaTeX of piped text dynamically scaled based on the amount of text and screen size.
Has anyone seen a utility that does this?
Desired input: text (via pipe)
Desired output: translucent text dynamically sized to fit screen dismissable by hitting a key or changing focus
