Most Chess applications with in-built databases have auto-play. The free and very popular SCID does that as well.
Open up a database, pick a game + set time / move and push play. This really helps if you pick your game database to contain the openings you play often.
Though I've also found it fun to follow live blitz games between Master+ players because I get to see the time taken per move as well.
Since I have been hearing so much from gms and ims that "quickly thumbing through master games for a few seconds eachs helps you recongize patterns" then I suggest chess.com quickly makes a program in whatever language that I can load a huge list of games in .png format with slow, medium, fast, and super fast speed option with start, stop, pause, and analyzise buttons. If chess.com can't or doesn't want to then does anyone know if someone already made this and where would I get it?
