Rasterbator is great for making posters with your own printer. Example of one of my goddesses
these aren't really "hacks" but fun ways to add to the goon experience regardless:
buy some porn magazines! super hot and fairly cheap way to add more smut to your arsenal and it feels super pervy flipping through them while gooning to porn on your screens (especially if you cum on them...)
don't ignore the atmosphere of your goon cave, it's just as important as all of the porn itself!
RGB lights are awesome for setting the mood. a lot of people use those LED strips, or if you want something less permanent (that doesn't scream WELCOME TO THE GOON CAVE to all your visitors) go for a cheap video light like this. I can only set up my cave when my partner's out so this is great for me: it attaches magnetically to the TV mount and i like to set it to the "scene" mode where it slowly goes through all the colours of the rainbow to get my stoned and porn dumb brain even more entranced
another redditor spoke highly of using incense/diffuser to give his cave a "gooning scent". he has a specific smell he uses only when gooning to get him extra triggered. i do this sometimes but i haven't found my goon scent yet haha
also +1 on a projector! totally life changing and there's plenty of >$100 options on amazon, especially since Black Friday is around the corner.
good wireless/noise cancelling headphones are key too. i like to mix a bunch of sounds when gooning: JOI/hypno audio, music, ear licking ASMR and sloppy porn sounds all at once. So hot being able to walk around and admire all the smut on the screens with that shit playing in your ears
have fun in the goonhole addict!
