ICYMI: Finger speakers and sumo-bots and mini-silk screens

Now with 100 percent more guest host!

Today on In Case You Missed It: The SIGNL strap Kickstarter campaign wants to put a private phone speaker at the tip of your finger. Plus, Japan combines its two favorite past times -- the graceful art of sumo and autonomous robots -- into a kickass, white-knuckle sport.

And what is this, a silk screen for ants? Nope it's a itty-bitty, teeny-weeny machine for printing fashionable designs on doll clothes. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
