I recently just bought the laptop I am typing on right now, thus, (I always wanted to use "thus") I haven't had time to put my own custom "deco" on it.
On my last computer, my brother had been throwing out a bunch of old National Geographic maps, so I cut one to the size of my screen and glued it on. lol
Even worse, afterwards because I needed my raspberry pi for a project, I taped a raspberry pi zero to the back of it, and then taped a USB plug to the back to power it with the port on my laptop. Surprisingly, its still on nice and firm!
But, before I totally ruin my computer, I was wondering, How do you all customize yours?
