There are two Hybrid cars that look "futuristic/different:" Toyota Prius and Honda Insight. It is because they were built as "maximum mileage hybrids." In other words, they use the hybrid technology to maximize the mileage you get out of the vehicle. Since they were designed as "new" vehicles to deliver high mileage, the "look" of the vehicle was pretty much predicated by a need to minimize drag coefficient (how hard the car has to fight against the wind to move forward).
There are several models, current and "coming soon" of hybrid versions of standard vehicles (including the Camry you mentioned, as well as Honda's Civic and Accord, and SUV's like the Toyota Highlander and Ford Escape). The only caveat you should note is that some manufacturers are looking at hybrid power trains primarily as a means to give a car more power than necessarily to increase the mileage, so when you look at the mileage of the hybrid version, it may not be significantly different than the non-hybrid version.
EDIT: And with respect to alternate fuel sources, you have to deal not only with the cost of development of the vehicle, but of the refining and distribution of the fuel. Electric cars, even if they were usable as a "normal" car don't help much because they are effectively drawing power from an electrical grid that is primarily generated from fossil fuels. So you look at other options, like fuel cell vehicles. That's great and all, but an infrastructure of fuel cell refilling stations won't happen overnight...I'm just saying it's more than just the cost of the car development, but the supporting technologies as well...
As far as the tax break goes, that's true and getting even truer next year...
That is, more or less, how hybrids charge the batteries, from the tires when the car is coasting or braking. Obviously not in other situations, as the drag of the generator on the system would end up costing you gas mileage.
Looks like my price per fill-up is going to go over $20 now....sigh...
