The “V” and “U” shaped ones look like that really simple kids’ cipher where the letters of the alphabet are put into three tic-tac-toe boards, with different shapes, and with or without dots.
Klepto21, did your friend send you this Jpeg, or did he send you a paper copy, and you scanned it in yourself? If it was paper, do the colors around the “letters” look like they do on the paper?
That depends on your monitor’s calibration.
My name is Ethan, so I don’t think my name is in there.
He sent me it as a Jpeg, I did not scan it in. (For all I know he got it from someone else, too)
English is definitely the language, though I wouldn’t be surprised if he used some lingo or slang.

Backwards “C” with the dot: 4 occurrences
“/”: 4 occurrences
Sideways “T”: 2 occurrences
Sideways “Y”: 2 occurrences
“S”: 2 occurrences

That’s exactly what I had written down, and noted the double sideways ys figuring there’s only so many words that have the 2nd and 3rd letter the same and are of 6 length.
I like the 180º rotation, and I think there might be something to the fact that all characters have some form of symmetry.
Only other thing I’ve been able to think up is that the / might be a space, and the space something else. Of course, I have no clue for sure.
I came up with this, :
t__, e _e set tither.
(assuming those are the characters, and its not flipped)
I was asking because the colors look like what you get when there aren’t enough colors in the image format, and the software just picks a nearby color. In fact, it looks a lot like 4 bit color. My monitor calibration isn’t going to matter much.
Maybe the word blocks on the left must be fit together to complete a square on the right.
It’s Futurama’s Alien 2 code:

It says
WOW, YOU REALLY ARE AMOSER
But I think it’s supposed to say
WOW, YOU REALLY ARE A LOSER
Thank you, aktep. You win 100 internets. And I win $10 
Seriously thanks, my friend is going to be impressed.
How does it work? It’s obviously not just a simple substitution cipher, as ‘WOW’ doesn’t have two of the same characters in it when encoded.
According to wikipedia, each letter is its own value (in mod 26, presumably) plus the sum of the values of the previous letters.
So the first letter is just the 23rd alien letter (W), but the next one is the value of O plus the value of W (15+23=38mod26=12). Using the order in aktep’s link, though, it looks like that’s incorrect. It’s actually the sum-1. Indeed, if I encode the string “AAA” I get three of the first symbol. If I encode “BBB…” I move through the alien alphabet one letter at a time.
So does this mean that aktep is the moser, or Klepto21?
You number the letters A-Z as 0-25, and add the value of the current letter to the previous letter. Then you have the symbols 0-25 and loop through them.
So for WOW, you take symbol 22 (which is the 23rd, since you start with 0), add 14, which loops you around to symbol 10 (the 11th), then add 22 which gets you back to symbol 6 (the 7th).
Of course, that’s exactly what you said but this is the “dumbed down” method they used to explain it on the Futurama “Benders Big Score” DVD, which I had watched only about 30 minutes before seeing this post which is the reason I recognized the code 
DAMNIT!!! I KNEW it looked like Futurama language, but I was looking at the wrong one! GRRRR!
