Lego Star Wars (and Indy and probably the soon-to-be-released Batman) have become my favorite video games ever.
Over on the Replica Prop Forum, one of the members is doing a run of 1:1 sized Lego lightsabers with acrylic blades in a variety of colors (I'm getting blue).

I probably won't have it in hand until early November, but I can't wait to add this piece to my collection.

"Dear Santa Claus. I have been a very good boy all year and for Christmas I would like.........."
That is a pretty cool piece, very unique indeed and would look great displayed with other Lightsabers.
