Cannot show the right screen

[bestfc]

The job is great. Code is few and easy to understand. From this, I tried vysor which can control android from pc(chrome plugin). that's great too.But no source could be found. and then I found RemoteDroid_web from this job. but it can not work rightly. websocket is corrected builded . Data is received by websocket in the demo html. But the html just show a grey block.No screencast.
