Back in the old days, there was an operating system named after transparent, glass-filled wall apertures numbering in mid-90’s. This operating system was designed to run on computers with CRT screens, which actually needed software to upset the patterns of light they generated, called screensavers.

This operating system had just such software, in a number of different variations. One of these created the “illusion” that the observer was travelling through space, passing stars. This is the subject of this week’s challenge.

Since the very beginning of MooTools you can only pick the right components that you need with the MooTools Download Builder, to ensure there are no useless bytes going through the wires. But this means you still download browser-specific code. What if you could optimize the code further by removing unnecessary browser-specific code?

The good news is, you can optimize MooTools builds to remove specific (IE) code! Packager has been used to concatenate builds since MooTools 1.3. Removing certain code blocks, like MooTools 1.2. compatibility or specific IE code is one of the features of Packager. Lets see how it works. We begin with downloading Packager.
