Why I love '50's robots

I'm not a huge science fiction buff, but I did go through a phase in 6th grade where I read lots
of sci-fi books featuring robots. I never collected robots as a kid, as toy horses pretty much
had my heart. Fast forward to my early adulthood, and I became entranced by those crummy
Japanese horror movies that were so badly dubbed. I was crazy about the monsters in them...
the more rubbery and clumsy the better. Some of the movies also had robots in them, and
I think that's when my love was rekindled. I started collecting robot toys (mostly knockoffs) and was so taken by the fearsome way in which they were always portrayed on the box art.
The paradox is: here's a primitive looking thing with dots for eyes, a grill mouth, an antenna
on top of its head. Frequently it's painted a primary color. Robots like that are supposed
to be scary enough to intimidate everyone. To me they just look charming and vulnerable
in the same way a 3-yr. old kid in a Batman costume looks charming (and not scary.)
It also amazes me how much character can be expressed by dot eyes, a triangle nose, a
rectangle mouth. I wanted to see if I could capture the same feel when I made my faces
jewelry. Even if I set out to make identical faces, they're always a little different. And when
I get a bunch of them together it just cracks me up...I feel like the alien in the room!
