What the heck is this bike and where do I get one?
 
This bike solves the problem of visibility among dense traffic while riding a recumbent (actually a semi-recumbent) bike: https://www.youtube.com/watch?v=GEhLYKJA9pQ. What do you call this thing? Is it probably a home-made one-of-a-kind, or is someone making these for sale? (If you can't watch the video, here's a clue: this guy is riding along a busy city street in congested traffic on a crank-forward-style bike. You can barely see the top of his head at first, and he surely can't see much of the traffic ahead, so he does something to the bike and suddenly he's riding a tall bike. Then when he gets a good view he decides not to continue that direction of travel, maneuvers among the cars, makes a U-turn, and whoop he's back down as a semi-recumbent again, then zip he's up to a tall bike again.)

I've never had problems seeing in traffic on my recumbent. It's a not-so-low Easy Racers Gold Rush, so I see over many cars and through most of the rest. My eye level is close to that of many uprights.

That's a neat bike, but pieces that move while riding along worry me. A little wear in the main pivot and that thing's going to get wobbly.

Interesting bike that may be a good speciality bike to ride is high density big cities. But then the stiff necked fools of the UCI wouldnt call it a bicycle tho.

I seem to remember seeing that video, or at least one like that, several years ago. It was a one-of-a-kind homebuilt, never made it into production. It made me wonder what kind of power it used to extend up. Compressed air? Obviously, not a recumbent even in its low form since it has no seat back, a saddle, and leg length adjustment is via a seat post. We'd call it a convertible Tall Bike to Crank-Forward.

Personally, I think people are even less likely to see a cyclist who's above their field of view than one who's at hood level.

Ah, like a Transformer (from 2006) or a Switchbike (here @ Eurobike 2007) with extended fork and stays. George Reynolds built a convertible upright/recumbent in late 2000. If it's like everything else in cycling, somebody probably made the original in the 1890s.

AFAIK none of these ever reached series production.

This isn't obvious, but it's probably true. Drivers aren't used to seeing "just tubing" with the occupant well above and I'm sure it wouldn't register in some drivers' minds what they see in front of them.

Spring counter-balanced, I believe, like a garage door.
