I made original rack back in 2008, first it was more simple without any Vahi, gold Ignika, gold Kraahkan, gold Hau. After some time it evolved from this (https://i.imgur.com/GDOabAk.jpg) to that (https://i.imgur.com/EfaM7NN.jpg). Main idea is to show all the most characteristic Masks from G1 Bionicle. Mask of Creation from G2 is here because there wasn’t any released in G1, and I wanted all 3 Legendary Masks together.
Order of masks isn’t random. Toa Mata masks shows beginning of Bionicle, then Masks of Light and Shadow shows next big chapter in Bio story, and then finally Legendary Masks. I also tried to keep it all symmetrical.
In last time I get two Ignika’s from 2006, from Shapeways, one in VNOG Style, second in Bionicle Heroes Style. And PLG Kraahkan (really magnificent mask).
With that I can now say, that Rack is really complete. It stands proudly on my desk.
Here how it looks on my desk (it was yet old version of Rack):
