The 5 little sketches in the lower right are coming to you from Yongfook.com
I've been reading this JET's blog since I arrived in Japan. His writing is really interesting and recently he added the sketch feature. Anyone can add a sketch and the most recent 5 will be shown on my website. He has it set up so anyone can add the sketches to their sites.
Most of the sketches are of poo and genitalia but I like that there will be something new and very random. So even if I don't post anything there is always something strange to see on Gotsu Girl.
If you want to make a sketch (and see it show up on this blog) go here.
