Microsoft has released the source code of its 1990s-era chat client, Comic Chat, as open source on GitHub. The software, which presented conversations as comic panels with illustrated characters and speech bubbles, was first released in 1996 and was known for introducing the Comic Sans font. The release allows developers to explore, learn from, and build upon the code. The project is seen as a nostalgic artifact from the early days of the internet and a reminder of the experimentation that occurred during that time.
