Well that is ironic. I click the link and get thrown a Varnish 503 'Guru Meditation' error.
I was surprised to see this story because I remember reading another article years ago on the same thing being done. The reason that one stood out was because it vaunted the use of Apple Mac machines being used to 'recover the lost art' due to how ancient the Amiga was and that it took them 2-3 years to manage.
At the time, I couldn't work out why they didn't just get some second hand Amigas off EBay and use them to convert the art to a modern format. It would have required a lot less stuffing around and been quicker.
