Fun Computing Backdrops by Gnu
Three versions are included in the archive:
FunComputing1080p.jpg - original image by Gnu.
FunComputingAmiDock1080p.jpg - variation by Gnu including a 'shelf' for AmiDock, similar in style to the OSX dock. You will need to centre your AmiDock at bottom of screen, set a scale factor of 75% for the icons and make the AmiDock background fully transparent.
FunComputingAmiDock1080pCropped.jpg - same as the above but I have cropped the image so the AmiDock shelf is still visible when the Workbench titlebar is on. Set 'Layout' option to 'Tile' in WBPattern for the best results.
