Japanese hologram concert and music videos

Was poking through the LA Times when I came across this interesting story about hologram-based pop stars. So I followed the links over to Youtube and was floored. Some pretty amazing technology involved in presenting a “live” concert with real musicians, singing fans, and a totally computer generated singer named Hatsune Miku.

Actually like this next song a bit better–> Just be Friends by Megurine Luka (I say it is by her but she basically exists only in a computer).  I may need a shrink soon.
