Extremity unbound
http://www.extremescience.com/
There are many extremes in science: extreme weather conditions, extreme natural disasters, etc., which play havoc with the lives of people. But extremity can be interesting and so this website is dedicated to all such extremes. You can learn more about disasters like volcano eruptions, tsunamis and earthquakes, look at the world records related to these extremes and, of course, you can look at some of the extreme creatures in the animal kingdom as well.

Zipping made easy
http://krun.ch/
If you’re one of those people who constantly need to zip their documents, here’s a neat little break from WinZip and WinRar. Krunch is a relatively unknown but rather interesting online tool that you can use to zip and unzip your files. All you need to do is upload files from your PC to zip them and then download them once unzipped. The only bothersome thing is the limited number of files (10) which you are allowed to zip but even then, Krunch is a refreshing change from WinZip.

Whether you host your own website or maintain a regular blog link, buttons are always a must-have for some much-needed promotion. This website has a very cool button generator; all you need to do is select the style of the button, colour scheme and text and your button will be generated through a mere click. However, you have to find some way of hosting the image of your button, if you want to use it as a link.
