Bijostagram - Shows Only Beautiful Girls From Instagram

Bijostagram (bijo = beautiful lady in Japanese) is a new Instagram mashup from Japan to pick up only photos with beautiful girls. You open the page, then it refreshes periodically.
The site was backed by a algorithm to detect beautiful girls photo only, developed by the creator hirotmb, and the frontend Javascript is supported by @amachang.
We introduced another Instagram mashup for cats photo, Nekostagram last week. According to Einstein’s no Denwabangou blog [J], there are many of similar category-specific Instagram photo viewer sites appearing by Japanese web developers.
