this would be similar to the previous post;
KNIdea: Small signal for distance places
that was, communicating with their gf/bf, using ambiguous communication tool.
sending the paired object's information
today's idea is using almost same idea, about sending "internet information"
like facebook, skype, gmail
in detail, for example, what if we could have a domino which has our friends' (in facebook) face picture. and it turn over when the friend went offline, or stand when the friend comes online.
we can confirm those information from website or software, but it means always from display. we have no choice to confirm those info without turning on the computer, even the g-mails
then, what if we could have dominos like this??
then, we could confirm whether your friends are online or not
or it can be designed like this :p
