As I promised a long time ago, here's my collection as I usually display it on my shelves.
The two shelves on the bottom left side are dedicated to 2001
Above the shelf with the Tarakava there are two shelves for 2002
2003 is on the bottom shelf of the right side (ignore the Napoleon minifig and the big Minecraft box)
2004 is just above 2003
And then there's 2005 on the side
2006 is relegated to the small closet under 2005 (I try to forget those sets exist, cause I don't like most of them)
(look at that nice 06 bad guy!)
2007 is kinda randomly placed wherever there's space, just like 2008 and 2009, so some of the sets are in my closet, some on the remaining shelves, and some in blue bins in the living room with the 2010 sets
(sorry for the foot in the picture
And then there's 2015 and 2016! (with room made for the upcoming wave)
Bonus! Here are pictures of the drawers where I keep the system instructions, the big folders of Bionicle instructions, the (WIP, I still need a lot of stuff to complete it) books/comics collection, and the place where I keep the (complete) Slizer collection, some Roboriders and the collectibles (Slizer disks, Roboriders wheels, masks, disks, Krana, Kraata, Zamor, Squids, Rhotuka spinners)
I also have other stuff, but it's not really Bionicle related.
Pretty nice collection, right?
