VIM themes
General hints:The screenshots are taken with the Terminus font. See also my Article about tiny fonts.
The vertical bar you see is a helping highlight that is offered by recent vim versions (try :cursorcolumn to toggle it).
If you are curious what some other things are (like the indetation markers) and how they work, take a look at my .vimrc. Note that the encoding is broken with that file so the "set lcs" part is probably not copy-pasteable, follow the instructions in the comments above that line in order to find out how you can make your own unicode-lcs.
