Problem: you’re bored with the look of your computer’s virtual desktop. Solution: grab lots of beautiful icons and then learn how to tweak your interface. Voila!
Problem: there are some great Macintosh games that you haven’t played in years because your old Perfoma 631CD is sitting in an attic somewhere. Solution: grab a copy of BasiliskII, a 68K Macintosh emulator, along with MacOS 7.5.3, a ROM image, and a cool utility for creating virtual Mac drives on your non-mac filesystem. Learn how to put it all together with some help from this guy and amuse yourself for hours. Then, after you’ve sickened youself with all this geekiness, read a book or something (and not one about networking or the latest JDK).
