Yesterday,

we made a post,

 about jig-saws, 

 well here is another, slightly different one,

 Strata is a sculptural puzzle designed to engage our sense of touch as well as sight,

 although not yet available, it will be hopefully be marketed in three sizes, 

Strata 16 Series: 4x4 grid (16 pieces)

Strata 24 Series: 6x4 grid (24 pieces)

Strata 36 Series: 6x6 grid (36 pieces)

it looks so easy, but I am betting it is a lot more difficult than you think,

you can support the venture on Kickstarter, and no I am not on commission, I just thought if you like jig-saw puzzles this one looked neat and I think will be a brain teaser to complete.
