I grew up on PC's but had not heard of Neko until somewhat recently. Back in the 1980s, Naoshi Watanabe created an MS-DOS graphical cat named Neko. I'm not clear on what it did back in the DOS days but it was quickly ported to the Macintosh in 1989 and would chase your mouse around the screen. That's it. It's just adorable and fun.

The full history is worth a read. It was eventually ported to Windows, officially licensed by IBM for OS/2 and the author even eventually declared the images as part of the public domain. Because of that, there's a million variants and offshoots of the program. The adorable lives on.

Maybe I should install WebNeko around here....
