Show HN: Flashback – an agent skill that references 127 years of design trends

Hi all! I was recently doing a live stream session at Build and created the start of a tool called Flashback. I wanted a way for agents to look through the history of popular design so you could reference different trends throughout time. I didn’t finish on the stream, but I kept coming back to the idea so ended up shipping it as a GitHub pages powered Skill and human browsable web site.

I think it’s really interesting to see how design has evolved since 1900, and I learned a lot in this process.

The repo is here: https://github.com/toby/flashback
