HEllo all, i bought some LED pixels of the internet, I cant seem to get the ws2081 library to work.
Just to make sure would anyone know what interface/chip used on these LEDs I bought? http://www.ebay.co.uk/itm/110767959914?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Four wires - most likely ws2081 ...
Common anode RGB LED? (can't open the link from here)
WS2801 should work.
(not ws2081, digits are swapped)
I meant WS2801... 
Could also be the LPD6803 or as the chinese label it: IC1010. Those are the little brother pixels of the WS2801. I have working code for both, hit me up if you want to have the details:

Depending on the manufacturer it can be very difficult to determine the type of IC on your strip after buying. My LPD6803 do have writing on the LED so be sure to take a look at that!
Thank you for the replies! So after trying various different codes and failing, I decided to contact the seller. Luckily he actually knew what he was selling which was great 
turns out that actually, they are LPD5903. Looking desperately through google I came back to the FastSPI library used in other modules. Google Code Archive - Long-term storage for Google Code Project Hosting.
Searching the page ctrl f "5903" I find this comment:
I'm currently using an Arduino Uno, IDE V1.0, to drive a string of 550 LPD6803-like RGB leds (Actual chip says UCS5903 but it drives as for LPD6803) and it's working brilliantly.
So thank you fexduino! I will have a look at the material you have supplied me tomorrow. As I am currently half through the hobbit!
I really do hope this works! Last time I did something like this for a GLCD and I could never get it working. This time i spent quite a bit of money assuming the ws8021 was being used! :S
OK, I couldn't handle that the LEDs were on the floor just waiting for an upload. Tried them with the 6803 on the fastSPI library. They seem to be fully operational.
......
Even through this post I felt the need to create a quick pattern. (: I may create my first video On how to get these working. I haven't found many on youtube that explain these in depth. I might go into the detail on what you need to do. Ensure what pixels you get etc.
I wonder on what to create! I might install these on something cool first! Or get some more!
