It's so funny, I want one, too. What would it cost?
Edit to ask: what does the signage look like as you navigate that atrocity?

A lot more that a standard cloverleaf due to all the extra overpasses. What I'd like to know is what it does better enough to justify the extra cost.
I don't see signage as being a difficult problem.
Higher off/on ramp speed lessens congestion. They did that to one of the intersections in NJ and it still causes some confusion because most people think driving is a right, not a privilege and don't care to know how to drive.
It reduces the number of off-ramps, the second-most-common place where accidents occur (on-ramps are number one).
Compared to a standard cloverleaf, it allows a higher speed, so merging is safer.
It reduces the cost of erecting and maintaining signs. (There's still two signs, but now only one of them is on the Interstate itself.)
It probably doesn't cost an extravagant amount more. Land acquisition is a significant cost (not just the price of the land -- there are legal hurdles, environmental issues, and a lot of other factors), and this design needs less land than a standard cloverleaf. In this case, it looks like they would have had to shift the horizontal Interstate down in order to build a regular cloverleaf because of the lakes.
Say they're Interstate 1 and Interstate 2. Normally, you'd have a sign on Interstate 1 for the Interstate 2 North off-ramp and a sign for the Interstate 2 South off-ramp.
In this case, you have a sign on Interstate 1 for the Interstate 2 off-ramp, and then a sign on the off-ramp for Interstate 2 North (bear left) and Interstate 2 South (bear right).
