Clean Up Campaign

I asked K to help me to make a DVD for my master exam.
We edited the video of performance "Another Time" into 5 min digest version.

Lately, my neighbors make a mess which I really hate.
We have a common terrace in our place.
It's an open space for everyone who living this building, but we have to keep there clean.

I made the text "THANKS" with littering cigarette butts and bottle crown cap as warning.
They should clean it up themselves. I hope it makes a difference.
