See that you've mentioned Max already, great inspiration there! Thank's for mentioning my site as well, hopefully there can be some things of interest. Writing on the english mirror site of the tips section, will hopefully be ready soon. A lot of translation to do...
I took a look at my Favorites and found this collection, some in english some in japaneese, use a translator or just look at the pictures...some are really worth it.
