I like how that blog / website looks with that ASCII header! Often I wish I would come up with such a design. And yes, I also like PNG a lot :)
I've been using this generator for years for ASCII headers: http://patorjk.com/software/taag/#p=display&f=ANSI%20Shadow&...
Oh nice! That seems to be using the tool 'figlet' (or maybe toilet, from libcaca), and the font is banner3-D, that's available here: https://github.com/xero/figlet-fonts
If you install the figlet (or toilet) tool and clone that font repo you can do a :
figlet -d ./figlet-fonts -f Banner3-D My text
'##::::'##:'##:::'##::::'########:'########:'##::::'##:'########:
