The tablet thing was much, much harder than the flashback but strangely, I actually like the flashback better. Though the tablet is a much more difficult and impressive project, I enjoy looking at the flashback script more. Of course, I have to give credit to Thrace for the idea. Then again, he did sort of steal it from the "Previously on your journey..." thing that plays when you load your save. :P
If you're interested, I've been working with combining time-based stuff with tile animations. This video shows a lamppost which is animated so that it flickers. However, the really cool thing about it (at least, in my opinion) is that it is only animated during night.
If you ever get any ideas for little projects, let me know. I've got a pretty busy schedule but as long as it's not something huge, I might be able to work something out. I enjoy tinkering with the game in order to add new mini-features but the problem is, I can't seem to think of anything. I usually get my ideas for projects from someone else (e.g., the flashback idea from Thrace, the lamppost idea from Manipulation, etc.). But if I get an idea, I'm usually pretty good at making it into a reality.
