Ever wanted to toy with HTML/CSS ideas right there in-browser, complete with real-time previews, syntax highlighting, and line numbers? Then CSSDesk from @pixelmatrix should rock your world.
Interesting simple generator for dynamic placeholder images for use in mockups and other demo layouts. You give it the image dimension, textual content, and color via the URL you then source directly in an <img /> tag.

Very basic grid generator that is great for embedded CSS in emails and the like. It’s also easily extended with additional functionality such as prepend-x and append-y.
(Thanks for the tip, @gregnewman.)
