In case you're not aware (and you may or may not be) Shiny Bits is having a bit of a conversion showdown...
You can go to their facebook page Here, and just look for the Wraithknight giveaway section... so far they have a little over 30 entries.
And yes, I said Wraithknight. Giveaway. As in the person with the most likes (although, I believe, ultimately the one they think deserves it) will get a free Wraithknight.
So go vote! Or go post your own conversion... the rules for doing so can be found on the blogroll *on this very site* (Blood Angels and Warhammer 40k).
Yes, I submitted a mini of my own. No, I'm not going to tell you which one it is, because despite how fitting it would be to undermine and sway the masses (I am a Dark Eldar player, after all) you should take a look and decide for yourself. Or post your own! Do it! Go! Now! The interwebs compel you!!
