title: How to beautify OpenLayers maps
body: <p>I need to build a web app that renders a Map with different markers.
  I think to use a solution as OpenLayers but i would like the maps to have a "better" look (as, for example, <a href="http://leaflet.cloudmade.com/" rel="nofollow">http://leaflet.cloudmade.com/</a>). Do you know any library that can be used with OpenLayers to improve its look?</p>
