Ps Going back to my disturbed childhood
I think I got really close to tracking down that strange slideshow I mentioned earlier. After searching yesterday, I came across Twisted Dreams by clones: Vol.1 & 6. Volume one was definitely very close to the style, but unfortunately those were the only two of the series I could find. Another one called Chiparus Slidarus was slightly similar, but again, I could only track down volumes one and three.
I guess this is an elusive kind of nostalgia eh?
