Many skins are just picture backgrounds. I stayed with the original ones, as they felt more coherent.

But there are rarities like https://skins.webamp.org/skin/06312f93d7b9499dc5dd0176133d6d...

It feels well designed as it's ready to read, and on theme.

Before that: Searches 'skin museum', very interesting but upsetting images found. Better to click the link in HN. (Yes, I often look for the links myself too see what other things I find on the topic)
