On my travels around the internet I found this video. It is a compilation of numerous anime opening sequences displaying the repeated imagery used over and over again. It's both interesting and rather humorous when you think of just how cliché most anime openings are. Whilst watching I couldn't helping thinking of several other anime I've watched that have most of the trends shown in this video. I'd recommend clicking on the video to watch it on YouTube rather then embedded as you can get somewhat higher quality.
