This is one of those things that you see and think "why didn't I think of that!" My wife could use this (she has a problem arm) and I could sometimes use it as well. An extra thumb on the
other side of the hand that is controlled by moving your toes:

QUOTE
This is not a prosthetic in the traditional sense, but a wearable human augmentation envisioned by [Dani Clode], a masterís student at Londonís Royal College of Art. The thumb is 3D-printed out of Ninjaflex and mounted to a printed brace which slides over the hand. One servo rotates the thumb, and a second pulls it closed using a bowden cable system ó not unlike that of a bicycle brake. Control of the thumb is achieved by pressure sensors in the wearerís shoes, linked via Bluetooth to a wristband hosting the servos and the electronics. We already use our hands and feet in conjunction, so why not capitalize on this intuitive link?

This kind of reminds me of a toy I had when I was young: "six finger!" Mainly I recollect that it was a spring loaded little dart gun that was in the shape of a little finger.

This is the commercial that sold me one!

I don't think I ever wrote anything with it!

Nah, that would've been my Crossman B-B gun; I had a shooting gallery in my basement when I was a kid and pumped my gun up a few extra times and it bounced back over my head and broke a window in my basement door!

My goodness, I vaguely remember one of my brother's having something like this.
I will have to ask.
Its very very cute!

When we were kids, we loved to make things like that, my favorite was a small iron pipe with a cap that you screwed on to the end with a small hole in it.
The hole was where the fuse of the cherry bomb was placed thru, and then a wad of toilet paper, and then a large marble. And a stolen cigarette from our mom.
And it was pretty darn accurate till our dad found it and it went away. I was grounded for a whole week, which seemed like a year to me.
