This has come up IC with the loss of some images that people were using on their nodes due to the transition to Grid 4.0, so just in case anyone's interested in replicating these images through ASCII or other means for use in Grid 4.0, you can go here:

They have all the images and the ads etc that were used in Grid 3.0.
