Came up with this little snippet, not fully knowing what the outcome was going to look like. Looks like a cheap water caustic imitation, not the fastest thing though.

SetWindowSize( 720, 405, 0 )
SetWindowAllowResize( 1 ) // allow the user to resize the window
// set display properties
SetVirtualResolution( 720, 405 ) // doesn't have to match the window
SetOrientationAllowed( 1, 1, 1, 1 ) // allow both portrait and landscape on mobile devices
`SetSyncRate( 30, 1 ) // 30fps instead of 60 to save battery
SetScissor( 0,0,0,0 ) // use the maximum available screen space, no black borders
UseNewDefaultFonts( 1 ) // since version 2.0.22 we can use nicer default fonts
// set print properties
SetPrintSize( 26 )
SetPrintColor( 255, 255, 0 )
