tig is pretty solid

I'll second that. I use tig daily.

Another tui I like is for networkmanager. For whatever reason, nmtui always seems to work better than the gui frontends.

I think PyPy deserves a special mention -- it's been a few years since I built it, but the last time I did it drew the Mandelbrot set as a progress indicator.

I use tig every day and it is easily my favourite git client. I especially love the staging view and ability to stage individual lines.
