1. elgooG (elgoog.rb-hosting.de/index.cgi)
This is a "real mirror" site of Google, as everything is reversed here. You even have to input your search terms in reverse alphabetical order. Moreover, its "ykcuL gnileeF m'I," which translates to "I'm Feeling Lucky," yields better results than the regular Google.
2. Googlefight (www.googlefight.com)
This website allows you to pit two search terms against each other to see which one has more search results. The results are displayed in animated numbers. Some classic combinations for comparison include "God vs. Satan" (God versus Satan), "Luke Skywalker vs. Darth Vader" (Luke Skywalker versus Darth Vader, representing the good and evil sides in the classic movie *Star Wars*), and "pen vs. sword" (pen versus sword).
3. Blackle (www.blackle.com/)
This website displays Google on an almost entirely black screen. According to the website's designer, "Blackle saves energy because most of the screen is black."
In response to doubts about its energy-saving effectiveness, the website acknowledges that the black screen approach only saves a limited amount of energy. Nevertheless, the website still claims, "We believe that every time you log into Blackle, it serves as a reminder that saving energy starts with small actions."
4. Goolge Loco (www.googleloco.com)
When you type keywords into the search box, each letter transforms into a different icon, and the entire search box changes color according to the changing icons. However, the search results are the same as those from regular Google.
