PICOL (PIctoral COmmunication Language) is an universal icon set for electronic communication.

The icons were made as a coursework by Melih Bilgil and attempt to provide a standardized way of communicating with application users.

Although some icons are confusing and the license requires attribution, these are the only criticisms about the PICOL icons.

There are about 520 icons altogether in the icon library, and you can generate thousands more with the icon generator.

Color Thief is a JavaScript library that can grab dominant colors from a picture.

Color Thief is easy to use and employs the canvas element for generating a color palette from a picture.

The script actually works (see demos in the homepage), and can grab the main colors even from the smallest image.

PCSS is a server-side CSS preprocessor that enhances the functionality of CSS and makes it easier to write slim and effective code.

PCSS runs on PHP (server-side), and enhances the functionality of CSS by adding variables, pre-defined constants, and browser detection to CSS.

PCSS also offers short forms of numerous CSS properties, and minifies the written code in the end.

Overall, this library is potentially useful for most CSS designers, and the browser detection is really an ass-guard as it allows you to skip a lot of browser-specific code.

Cue is a fascinating gesture icon set that aims to provide intuitive clues to touch application users.

Although the icons can look confusing at first, the idea behind them is very elegant.

As touch technology becomes more and more common in our lives, this icon set is among the first to try and set a standard that’s both universal (pictographic) and easily comprehensible.

About the icons themselves:

• Cue comes in multiple formats (PNG, SVG, Omnigraffle, and InDesign);
• Icons are released under the CC license;
• Icons take little space;
• Cue is still in development, and the icons are subject to changing for the better.

SimpLESS is a web-based LESS.js compiler that effectively negates the need for including the JavaScript library.

SimpLESS is useful, because you don’t have to include the LESS library in your projects as the result is pure CSS3 code.

It can also help as a tool for “extracting” code from LESS-based websites (there are a few). Besides, the less external libraries, the better.

OneFileCMS is a Content Management System that’s actually a single file. (Inception!)

The CMS has all the basic features an FTP client has, and users can update the pages via a built-in source editor. The admin interface allows interacting with files through something else than FTP.

Of course, OneFileCMS is very basic, but a 24kb CMS in one PHP file doesn’t promise much, does it?

You have to code your website’s pages, and this CMS, although an innovative solution, isn’t for the beginner or even for the intermediate user.
