what happens when you complete all the collectables?

I was just wondering getting tired of looking for them, I completed all the puzzles and I was wondering if something special happens when you complete the collectibles.

SPOILER




Your village population increases by +5 for each collection I think. Also, if you have v 1.00.4, you'll get a decoration at your research lab for every completed collection.

A sense of satisfaction?! I've seen some threads that indicate the research room gains decor...but I have not completed my collections so I am not sure. The tablet looks abit interesting to me. I am curious to know if it has some effect when complete.

I was wondering if getting all of the collectibles would result in completion of the final puzzle...guess not?
