Program computer graphx

College dropout here, I don't come here often. So last week I read a blog about people who made Amiga demos in the 90s. The ones that sometimes came with hacked roms, showing fake 3D effects, parallax colored backgrounds, matrices of sprites doing stuff and text flying across the screen in a sine motion blinking in all kinds of psychedelic colors and shit. And how in that text the programmers would go on and on about crunching framerates, screen blits, dma timing, all kinds of shit I don't understand about. Nostalgic shit. So, if you know what I'm talking about, I just want to know the name of a language, IDE, library or whatever, that lets me write programs that do something like that. Preferably a modern language.
Just a name I can google will do.
