As I said on the previous post one of the ways that new content is generated on the “read write web” is that existing services release their API.
Flickr did this and there are a large number of services that use either the API or the RSS feed to enable users to generate new images from Flickr images. I have tried only a couple – Color Fields Experimental Colr Pickr which lets you find photos using a colour wheel and Spell with Flickr which generated the image below. A Trading cards generator has been extremely popular with librarians.
Homework for this post is to try two of these services that I haven’t and write a post reviewing them.
