For a tmux status line as seen in the example image for the wemux project:
The session on the left in the example screen shot uses a patched font from the vim-powerline project. Inconsolata-dz, you beautiful creature.
To duplicate the left status line add the following lines to your ~/tmux.conf
set -g status-left-length 32
set -g status-right-length 150
set -g status-fg white
set -g status-bg colour234
set -g window-status-activity-attr bold
set -g pane-border-fg colour245
set -g pane-active-border-fg colour39
set -g message-fg colour16
set -g message-bg colour221
set -g message-attr bold
set -g status-left '#[fg=colour235,bg=colour252,bold] ❐ #S #[fg=colour252,bg=colour238,nobold]⮀#[fg=colour245,bg=colour238,bold] #(whoami) #[fg=colour238,bg=colour234,nobold]⮀'
set -g window-status-format "#[fg=white,bg=colour234] #I #W "
set -g window-status-current-format "#[fg=colour234,bg=colour39]⮀#[fg=colour25,bg=colour39,noreverse,bold] #I ⮁ #W #[fg=colour39,bg=colour234,nobold]⮀"
