Nice Work! This is on my to do future list. I know it's not the real thing but all the usual benefits apply to this build. As others have stated, if done right, it's pretty dam good.
I was thinking if there was a way to use a 3D TV? Play with glasses and add the depth of the Play field and toys. Most likely there would need to be some video card with software to do this. Has anyone any info on implementing this or if it would even make a difference?
