I get a 403 forbidden for all these links...

It's not obvious to me what the problem is. Maybe google drive doesn't like the number of hits it got to this one area. In any case, this is the base directory: https://googledrive.com/host/0B_Y4OBMHA7qRaTBGbVNaVFlYWWM/im...

I can't edit the previous post for some reason, so i'll post it again:

Original author here. Thanks for the mention! The project was done in 2004, first implementation in shockwave, later flash. I redid the whole thing in js+canvas a few weeks ago, finally with a much smoother zooming algorithm than before. Feel free to shoot me any questions you might have!

How did you do it?! Did you start out with a really high res digital painting, and then cut out the middle, zoom that part in, and repaint over it?

I love this, I happened to have Space Oddity playing at the time and it was an enjoyable experience the two work together well.

We worked with single steps of 1024x768 pixels size with a center part of 50% left out. An illustrator would either work inwards or outwards of the existing portion. Outwards that would give a photoshop document of 1024x768 with the previous step locked on a centered layer of 512x384. Inwards with the upscaled previous image of 2048x1536 as the frame, and the respective centered paintable area of 1024x768.

The illustrators then could easily blend their work into the other peoples artwork. The whole thing evolved very un-planned. There was no guideline as to what should be depicted. Illustrators just had to pick up what others have left for them. Best part of the process for me.

Actually pretty amazing, artwork and technology! So how exactly does it work? The art couldn't have been done in a JS canvas, could it? I imagine it's just a really high resolution image that gets zoomed into and looped back? That's actually hard to understand too...

It's a series of images at different zoom levels. Since there's no freedom of movement, you "just" need to leave a section in the centre empty, have someone draw a large image for that section, copy in a scaled down version of that image. When displaying it, once you've zoomed in a certain amount, you simply start copying in the next image in the series suitably scaled down, and keep zooming until that image fills th…

Definitely interested in how you did it. Also any thoughts on how you think it can be improved in the future
