What is a Poken? - what do the different lights in the poken hand mean?

there are the following light modes in your poken: a green, red and orange glow, plus the ‘light show’.

the green light appears when you have successfully pokened with someone, meaning exchanged your social business card data.

the red light appears when the two poken couldn’t successfully exchange data. you will have to wait for the red glowing to stop (or simply press on the glowing button once, then the glowing will stop, too), then you can retry to poken the other person.

the orange light appears right after you have pokened with someone but only have space left for 4 or less additional poken contacts.

the ‘light show’ appears when you press the button in the poken hand for a couple of seconds. it doesn’t hold a specific purpose except for simply entertaining with its groovy lights (and at the same time it will also tell you if the battery still works ;-) )
