Fake road sign advertisement

Creating fake road signs is fun and quite popular on the internet. I gave it a go and I found out it is not that difficult to create one using standard tools (ex. gimp). Here is the result of my first attempt:

Blogger Tag Cloud Widget

I wanted to have a Tab Cloud in my blog. However, blogger provides only the Label widget which gives only a list of the blog's labels.

I found this blog entry , which produced something very similar to what I wanted. I modified it so that:

  • it is more to my taste
  • allows for further development and easier modifications.

You can see the resulting Tag Cloud on this blog (collumn on the right) and also in http://www.papitsa.gr/

The installation instructions can be found in the original post.

allow further development.
