This is Go port of byzanz_window.py. It is very nice python script however it does not work with Python 3.4. So I port it in Go language. I test on XFce4 and LUbuntu. If byzanz-window does not work on your platform please report me via github issue.

% go get github.com/syohex/byzanz-window/cmd/byzanz-window
