Long ago, in a land far, far away, Takeshi mentioned the idea of combining an Orb yo-yo and a BK. I think his vision was doing some lathe work and nesting one half of an Orb in the base of a BK. This mod is pretty easy because the Orb cap upside down in the BK base very snug, which centers the light card automatically, nothing is glued. You have to cut and bend up the contact "box" a little bit, and drill a hole for one of the lights, put it together and POOF! It didn't take long to balance it since I had already put the hole in the crown. I have a little bit of video of it in action, waiting for a chance to throw it together and upload it...
