So I decided to use my cell phone, which has minimal videoclip possibilities at 320x240, hardly remembering how to even start a movie going since it's been almost 2 years since I tried the cellphone video. The water scenes though, were so interesting, that the videoclips turned out better than I thought they would. So I put them on Youtube for friends and then found that youtube now offers larger versions even from 320x240 but they've done something to make them more bearable when expanded that much.
THEN I found a link format that links us to an almost full-screen version, which is still mostly bearable, not ideal but it gives a feel for what you see while there.

There are only 4 videoclips - less than one minute each (except the last one is 2 minutes). The first 3 are okay at the larger size but the 4th one is probably better viewed through the standard frame on the page. That last one (4th) also shows a bit of the tunnel layout whereas the others don't -- but it's more pixellated as I was trying to combine 4 clips and was trying out various trial-ware.
Below the 4 video thumbnails are some for still photos that I took at 70mm zoom! despite being too close and the subjects being moving fish in a dark narrow space, so of course most are pretty fuzzy!
All this is to apologize for the fuzzy stills and the low resolution videos but I hope they give a general idea of what you'll experience there.
If you're in San Francisco, well worth a visit! Here's the one still that's not blurry, because the fish was strangely still
