GTA 4 mod lets you take selfies

Rather than use Niko's phone, you'll gain access to a menu of commands, letting you set specific facial expressions such as "angry", "surprised" or "whatever". You're possibly sat there thinking "this isn't a thing that people will want to do", but it is. It is a thing that people will want to do. 

GTA 4 isn't a big fan of being modded, but you'll find installation instructions on the mod's info page  For the most part, it uses the OpenIV Package Installer  but there's the extra requirement of enabling compatibility mode.
