IKEA using Drupal
IKEA is everywhere. With over 300 megastores in dozens of countries, it's one of the world's most recognizable brands. Chances are you have some IKEA furniture in your home — I certainly do.
With the help of Swedish Drupal consultancy NodeOne and the ad agency Futurniture, one of the company's websites, http://livethemma.ikea.se/play, is now on Drupal. This video-rich site makes heavy use of Apache Solr and Panels Everywhere; the theme is based on Precision, while Varnish and Memcached speeds everything up.
