DIY sliding closet doors. These are very very similar to what I was planning for our bedroom remodel this winter. However I'm going to use stained glass panels rather than frosted glass. And I will be routering a rabbit into the back to attach the glass, rather than using glue and mirror clips.
The Bypass Door: This type is usually made of two parts that slide in front/back of each other. It is the most common type of sliding closet doors. Sometimes there are more than two pieces (three, even four), especially if the closets are really big.
