First of all, I'd like to thank:
ikillyou121[link] for the great vector of Rainbow Dash;
SmittyG[link] for the absolutely cute and ADORABLE maid drawing;
Hawk9mm [link] for RD's cutie mark.
Thanks for letting me use their vector's/artwork for letting me print this out and put it on my DJ setup.
So when it's spinning, it looks kinda like a Sonic Rainboom, at least the base of it. When I was coming up with the design, I tried to just make it but it took too long, pixels were showing when I blew up the image to 300dpi, and doing this would've been easier. I decided to make an image that should simulate the rainboom when the turntable is spinning and it does if my eyes aren't following it spinning. Although I messed up and didn't realize until I got them today. While I was making the design, I forgot turntables spin clockwise...and her cutie mark is facing as if it should be spinning counter-clockwise. Fail.
The photo on the bottom was taken with:
ISO - 100
Exposure 15 secs
Focal Length 36mm
So it appears its moving faster than it really does but hey, if a rainbow sprouted out from the middle, it'll really look like a sonic rainboom, no?
