I just replaced the winter scene with this, penguins still work too
http://linux.alltechdevelopment.ca/planetary.jpg
Steps I took:
- open super terminal
- cd /boot
- mkdir message1
- cd message1
- cpio -i < …/message
- exit
- open /boot/message1/pback.jpg in gimp
- Used a background image 800 x 600 (same size as pback.jpg )
- Used gimp to design visual objects to align with those in pback.jpg
- saved out as flat image (no layers) as pback.jpg
- exit gimp
- open terminal again
- cd /boot/message1
- ls >> filelist
- cpio -o < filelist > …/message
- exit & reboot
Don’t know how to change the penguins positions but upon reboot
my new grub display comes up with the menu and penguins moving intact.
hope this is of interest.
