As unleaSHHed said, this is not a stego challenge, but similar.
I wouldn't say 'see the invisible' cos it's right in your face,
but yeah, 'you need to get the correct association'
And no, you don't solve this by thinking up all sorts of weird
logical possibilities of connecting the dots. Actually the name
is a misnomer.
I'd rather say that some of you must've already solved this kind
of chall sometime st some other chall sites, but you 'cant get the
correct association' with this one.
You might wanna rack your brains and try to remember if you've seen
those dots somewhere? Probably on some site that's 'the largest and
most popular general reference work on the Internet'?
PS: By the way, StarkHalo, you're getting close. If the other's can
figure out how he calculated the length of the solution, you might
get a better idea about the chall
