Im interested in seeing how ugly it looks too.
Ive asked Cheapmod if they stock white transparent Supercards, or perhaps even solid white plastic supercards.
They said they can only get them in blue, whereas they used to be avaliable in 4 different colours.
I guess if you get black lite, you wont notice how much it sticks out. Since the dark blue will tend to melt into the lites body.
About the size. I would also like pics of how the supercard SD looks on a ds lite. From theory, looking at a normal supercard minisd, that sticks out about half a centimeter, I would say an SD card sticks out 40-50 mm extra.
