Description: A tribute to Japanese mobile phone websites of the early 2000s (NTT DoCoMo 502i era). A single 240px column, no JavaScript on the front end, scanline overlay, a bitmap-style web font, and 138 hand-made 12x12 pixel-art emoji available as shortcodes. Shows 3 posts per page, the way a tiny screen once demanded.
