Has anyone made/thought of making retro computer FX?

I've seen so many incredible creations thus far with Filter Forge, so it's only sensible that I see many more! In particular, in the past, I've found a need to go through various steps to create lo-fi graphics. For example, to make something resembling an old Commodore 64 graphic, one could use the http://taint.org/tag/c64izer .

But there are so many possibilities within Filter Forge, which appear feasible: I also think of the fake LucasArts game "smoothing" mode; I forget the technical name but it holds a warm place in my heart. Also, old magenta, cyan, white, and black CGA graphics. And classic Mac dithering effects. As you can sense, these might make for some really wicked filters!

Anyone else into the idea of making retro computer FX filters?

Right now FF can't do a true pixelize like the one Photoshop has. The two FF methods; the "Tiling with Curves" snippet and the "Solid Fill" option for patterns only take a point sample instead of an average.

Ah, good old days with the Commodore 64. I thought their logo was a sideways jellyfish for the longest time until I grew up and thought about it in retrospect.

It would be pretty awesome to see a filter that emulates the appearance of old-school computer games though. Is there any component or technique that can be used in Filter Forge to limit the color palette though? Maybe some combination of Levels and Tone Curves, but I'd imagine getting an exact 256, 64 or 16 color palette, especially the standardized color palettes for those systems, would be pretty tricky as far as I am aware within Filter Forge. Although I don't experiment too much with extraction or channel components, so I'm not quite sure if it's actually possible(Although doing the palette shift as a post effect in Photoshop would be simple workaround otherwise I'd imagine).
