SKY VISION

Anyone who spent the Sunday on Flinders Lane could not miss this peculiar vision. People wearing what looked like the very first camera on their heads walked along the street in groups of five (four camera heads and one leader).

Curious as I am I had to ask what they were up to and apparently it was some kind of periscope looking up in the sky...

Anyone knows what this is? Maybee even tried one for themselves... I'm so so curious what they discovered:-)
