I posted on another forum some Strider comparison shots that maybe you might like to see. Here's 3 different views of the Genesis, arcade + X68k versions.

68k version's neat, even if it does appear to only have one background layer.
I know one comparison though, the MD version's the glitchiest thing in the whole world (apart from maybe Ape Escape).
We also managed to break the PS special version many times just by playing it normally.
