I am always in sight, but never reached. I mark the boundary between the known and the vast. Though I recede as you approach, I am where the sky meets the earth.

Press me, pin me, thread me through a hole, I'm a magnificent fastener if that is your goal, If I'm on the smaller side I can be a little tricky, But hit the big red one of me and things will go south quickly!

Can be hung from an ear or neck or hand Can go on a finger as a band First five asked Who Will Save Your Soul by singing All together, adornments for blinging

It can tell you to stop or go Or use to indicate a turn It can bring music to the radio Or a gesture to learn

I'm named for my number of legs, But the word refers to feet in Greek, I'm not a bug so don't be tricked, I'm useful gear for camera geeks
