Minecraft Banshees!

This is the Banshee from the game Halo (first created by Bungie, now owned by 343i), recreated in Minecraft by yours truly! I hope you guys enjoy, and I will possibly be uploading a map download soon!

Materials needed:
-304 purple wool (4 stacks and 48)
-62 gray wool
-6 white wool
-32 light gray wool
-2 levers
-ice is optional of course, but I feel it greatly adds to the "Banshee" effect

Special thanks to DeltaDragon222 for correcting me on the top of the hatch's color!

EDIT AS OF 7/13/2013:
World download is now up! Have fun making banshees in your Minecraft world! :D

Additional Notes

Ignore the other things in the background, I built the Banshees in my area for a build contest on the server I play on, lol.
