LIVE WALLPAPER: wallpaper engine. only thing on here that costs any money (its like 5 bucks on steam). im sure theres free alternatives but this one has a lot of presets and stuff so its less hassle and its what i use. might be a bad idea for lower end pcs tho

CUSTOM TASKBAR: retrobar on github (lots of different options)

CUSTOM CURSOR: theres a lot of places to find these, but rw-designer open cursor library is a good place to start

DISCORD: betterdiscord, im using the clearvision v7 theme with a custom background

EXTENSIONS (these are for firefox, might or might not exist on other browsers):

tabliss for the new tab theme

stylus for tumblr -> specifically the 'tumblr - custom dashboard pallette' theme for colors + bg, and this for the pre-twitterifcation layout

enhancer for youtube for custom youtube colors
