Plenty of historic technologies such as the VCR, camcorder and CD player made their debut at the Consumer Electronics Show. There have also been a lot of failed gadgets, bizarre creations and a general theme of weirdness.

Cameras are everywhere.

You’ll see concept cars that look incredibly unsafe to take on an actual roadway.

Talk to the hand? Here we have a cyborg showdown.

Robots dole out high-fives.

Movie characters sell guitars.

There are startling backdrops to keynote speeches.

Come for the gadgets, stay for the teeth whitening.

Everything goes up in smoke Friday. So enjoy the conference’s unique culture while it lasts.
