The cheap variety is on the left from Forever 21 and an affordable €23,75 (here). The right pair is a serious upstage from Gianvito Rossi for €426 (here, not the ones with transparant sides, btw).
Ps: I get into a slight state of childhood with holograms. It's not Starwars or Startrek but actually the sugary flow of comics with cute & dynamic heroines such as Jen and the Holograms that gotten me hologramic!
The pre-SpongeBob era!...I think Ren & Stimpy were the 1990s version of SpongeBob sarcastic realism. However, before that there were lots of Cartoon heros & heroines hologramming or superheroing around.
