2 necklaces one yellow 3D effect

I can't find either of these online. The yellow 3D square one has glass beads, all ranging in size and the squares are plastic I believe. The elephant one has matching earrings and green glass hoops and heart shaped chain.
Any ideas on era, country etc. ?

Thank You

 

The yellow one in the top picture looks like a home-made necklace from common beads.

Is the last picture a different yellow item? In the first picture, the square beads look three-dimensional but in the last one they look flat?

 

They are flat but 3 dimensional

 

So they're fairly flat but made to look like they're cubes? If so, the effect is working on my brain... I keep seeing them as cubes in the first picture!

 

Yeah, they are about 3/16" thick and for sure they give the brain an illusion

 

me too Pat

Thanks cxgirl, yeah they are trippy indeed, I love em..
