Okay, here's how this works. Every hour or so, Walter reads a different book. The book he reads corresponds to the actual time on your computer, and there's one book for every hour (I made it easier to tell because there is a number on every book that corresponds to the actual hour of time.)
Some books I've actually read, and others, I had to do a bit of researching. In case you didn't know, the original book Walter was reading from a panel in the manga was The Moon and Sixpence.
Additionally, I wanted to change the color of his pants and tie to correspond to a different day, but because of the bad lighting, it's probably too hard to tell. If it works on your monitor, then great, I guess. Sunday is most obvious though.
This was actually a pain to test because I had to keep switching variables, or else waste time waiting an hour. I was also going to add more stuff, but AS3 is giving me headaches, so I guess I'll include them later when I figure out what went wrong.j
Haha, I must be evil, making people wait for Walter to switch books.
