The star of the recent Comic-Con event was Homer. A spectacular three-dimensional hologram of Homer.
Homer just walked on stage during a session and made small talk, as can be seen in the following video (this video has received almost a million views!).
This appearance could also be last of 3D Homer as Hologram USA started a court procedure against Twenty-First Century Fox. The allegation is that Twenty-First Century Fox is using the (hologram) patents without any authorization or license. Well, not everyone can laugh at Homer.
