Lines and Colors is published on WordPress.
The template is a variation of Aesthetic theme by Dilip V. I’ve pretty well hacked the template beyond recognition, so any excesses are likely mine.
“Sociable” (tagging icons under each post) is a plug-in from BlogPlay.
Body copy is Verdana, headings are Arial.
Background pattern by squidfingers (modfied).
