Late last night I finished programming something I have been playing with for a the last week. It is a tag cloud using the "GetPopularResults" API call from the eBay API and forcing a curve for the word font sizes.
The upshot of this little bit of programming is the image shown to the left of this post and you can see the live version at example eBay TagCloud I will post in the near future a way that you can create your own version of this Tag Cloud and the code used to call the eBay API.
The Tag Cloud displayed is for category "1" (Collectibles) on siteid 3 (the eBay.co.uk site) and shows the top 30 words searched for in this category and site combination using the GetPopularKeywords call on the eBay API.
Of course due to the simplicity of calling internationally on the eBay API this cloud can easily be set up for any country and for any category which I am really proud about.
