Touhou wikia really is insane for trying to describe all which is touhou-related. After all, the pace at which new content is being made exceeds the pace of content generation of most other franchises combined. My nickname is redtails and I don't think I've made a lot of contributions to the English touhou community. I am the 'artist' behind this mosaic and the gigantic ZUN mosaic. Both were made using images acquired through a batch program I wrote in perl, called Tagbooru. A compiled x86 version of tagbooru is available at the download page of Tagbooru's project page.
