Some of the topics are web pages that reproduce hacker-owned PCs that appear in movies and dramas.
In movies and dramas, a brilliant hacker may call various windows on the screen of a PC to perform what appears to be hacking or cracking. This web page, named "Online Hacker Simulator", is a reproduction of the screen displayed on those hackers' PCs, with the alphabet falling like a matrix and the script scrolling. It's almost unrelated to hacking, but it's interesting that it creates an atmosphere like that. In addition to being able to freely select the items that can be displayed, it is also characterized by being able to specify detailed parameters such as color, monochrome, or green characters on a black background. If you use it instead of a screen saver at work, you may be able to give the impression that you are familiar with PCs.
