Create a new setup based on this package. Once you install the setup on a device it will open an FTP server so you can upload the BLOAD.txt file.
Once a BLOAD.txt file was uploaded the visualization will show the basic layout. All that is missing now are movie images. Upload them as assets to your account and then assign them to the Movie images list.
Set a FTP password. Once the password is non-empty, the FTP server running on the PI will accept uploads of BLOAD.txt. The ftp server is reachable on port 2121. You can find out the address by visiting the device detail page.
