I built this bookshelf in my spare time, and it didn't cost much, or take a long time. The wood working was quite simple (I just followed the plans.) I made it out of oak, and finished it with golden oak stain. I picked out some tiles by Totem ($20-$30) and placed them on the top, flush with the trim. I chose a design that I liked, but you can have any arrangement of tiles you want. Once the tiles were glued in, I grouted between them, and once the grout was dried, I wiped it down and I was finished. It was fairly simple to make, quite cheap cost wise, didn't take much time, and looks nice.
