This is a fairly low-content post, but today I learned that the source for many of the icons in Visual Studio comes from the Babel package:

The Babel Package comes with a collection of icons that are used in the IntelliSense completion lists and in the drop-down bar used for quick navigation. Most of these icons are arranged in sets of six variations, where each variation corresponds to the access concepts of public, internal, friend, protected, private, and shortcut. For example, you can have different icons for a method depending on whether it is public, protected or private.

Here’s what the icons look like, most of which will be familiar to any of my fellow .NET developers:
