The variety of Dark Side prisms that have been posted on the official Pink Floyd sites (Facebook, Twitter, etc.) have proved most interesting and it is clear that many fans have greatly enjoyed them. Ranging from much loved, and expected variants, to Miro and Dali influenced abstracts, and even the standard cover reproduced using liquorice and assorted beans and buttons, a huge amount of imagination and hard work from the team at StormStudios has now come to an end, and we can now find out what they were all for.

If you pay a visit to PinkFloyd.com, you can now see the completed grid with all the images now in place, but more than that, the overall image - a celebration of the album and its iconic cover - can be downloaded, free of charge, in three different sizes, so you can truly appreciate the detail and vivid colours.

Just as a reminder to our story the other day, tomorrow (the official UK release date of the album) sees Pink Floyd and EMI Music marking the 40th anniversary, as fans around the globe unite to turn a specially designed moon dark.

Starting at 00:01am GMT on Sunday, for the entire day, fans all over the world will be able to share thoughts and comments via Twitter using #DarkSide40 and witness the impact as the volume of messages combine to turn the moon dark...
