My first thought was perhaps some kind of collectible game thing, like Pokemon or something. The four coloured, differently shaped moulds/cases might be for different characters, like Pokemon or Ben 10 aliens, or whatever BBT nerds are into! What is the wording on the base? "Gold… something?"
I tried zooming in to get a better shot, but the resolution failed me. You can see a little better that it's a single unit, though.
It does appear to be some sort of game. Gold appears to be part of the designation of the yellow element, the label under the blue element looks like it has a blue background. No idea beyond that, though.
Web surfer girl get's a hit: http://chasingprops.com/the-big-bang-theory But it will take a bit more looking.
I need more search terms. Which episode, which season might help. It would appear there is quite the fan base for BBT props including lots of inquiries, what is ...?
Perhaps some kind of display for a crystal growing kit or something? I tried searching and can't find anything.
Those aren't crystals, all four look to have blobby creature shapes. Perhaps our Anime experts might recognize the characters from their mere outlines. Still no luck. Any other words on the toy would help, a different angle telling us it's cyan instead of blue or something. Those are most likely cartoon figures of some kind under the domes, the gold one looks like a bear.
Well I don't think it is a game because I found this website and it isn't on there. http://toys-chan.hubpages.com/hub/Games-Played-Seen-Big-Bang-Theory-TV-Show
That's excellent web surfing, but the list is incomplete. While it includes Jenga, it's mostly board games and the thing on the table is not a board game. For example, the card game Magic is played in an episode and is not on your list. I tried a search of games played on the BBT but it did not turn up the answer. If it's not a game, it could be some other kind of toy. There are slots that look like marbles or gum balls might come out the holes.
I wish I could read the word below Gold but I can't make it out. It really does loo like pieces of plastic shaped like crystals.
The picture is in Raj's apartment and I found a page dedicated specifically to it. In some of the photos you can see the 'thing' we are trying to figure out. http://bigbangtheory.wikia.com/wiki/Rajesh%27s_Apartment I'm a research finding nerd.
You found it! "JLA TROPHY ROOM: MULTI-COLORED KRYPTONITE REPLICA DISPLAY" And not a bear or figures. (I'm sure that price on the link is ludicrous, it was just the first link I found.) The word we cannot read is Kryptonite.
Haha I didn't look at the comments at the bottom where someone says what it is. Well at least I found the right page. Do I get a cookie?
