Creative Pursuits

Graphic Editing

Clipping Magic Site that helps you remove a background, in case you DON'T want to go at it with an eraser/masking tool for an hour or so (but why wouldn't you?) Best of its kind IMHO.
Wordmark Allows you to see a word or phrase in every font available to you. You need to give it permission to access your fonts if you have more than just the defaults installed.

Writing

Internet Typewriter A comfy web-based text editor.
Ohwrite Low pressure "word sprint" type site.

Jewelry making and other metalworking

Alberic.net Personal website all about metalworking. Has stories and tutorials about making and improving tools. My original bookmark pointed to this tutorial on replacing a jeweler's saw's thumbscrews with cap screws and wingnuts. It's also a portfolio site, as you'd expect, with some very fun pieces.

Zines and Bookbinding

Spectrolite (Mac-only :( ) Tool for creating risograph prints.
PDF Bookbinder "A program to create a bindable book from a PDF file" Very picky about the formating of the input file.

Misc.

Open World Shutter Tool for taking "long exposure" screenshots of games (or presumably any program, but.)
Videogrep Tool for clipping out every instance of a word or phrase in a video.
Pal "Pal let's you apply an eight-color terminal color palette to an image." Lots of option, but does not do dithering.
