Alternative to bi-fold doors

[Jason F]

I bought a house in a really nice area and I want to rehab it very differently then the way I'm use to. Instead of cleaning it up, throwing down beige Lowes carpet, painting the walls white and 'making things work', I want to create a very contemporary and customized look.

It has metal bi-fold doors and every piece of me is saying "paint them and throw them back up" but I want to see if anyone has any alternative ideas to these loud clunkers. I'm sure there has to be a opaque glass alternative or sliding something. Any idea?

I was thinking maybe save the hardware and build my own wooden doors with the glass inserted. That, however, sounds like something I think is a good idea until I start to see the final product.
