[ENDED] New puzzle at last

Bump for being stupid and too busy to solve it earlier.

Will there be more hints?

Last hour!

Solution:

• Part 1 - Find the puzzle.

The link is a lie. If you run the mouse over the link you will see a valid link, but if you click on it it leads to a blank page. Look at the source code, you will see why:

<a href="http://www.itstoohard.com/puzzle/VBksJ%CE%9AE8">VBksJKE8</a>

The letter K is not a letter K, it is kappa. I used a similar trick in my first puzzle. You have just to copy the code I wrote (the text, not the link) and paste it following the ITH url format (http://www.itstoohard.com/puzzle/VBksJKE8)

• Part 2 - Solve the puzzle

HINT 1: There is an offset
HINT 2: Message has 138 characters. Sorry, it will be a bit tedious
HINT 3: It is a bit obvious but... Focus on the picture

So... It is about the colourful picture. I said the message has 138 characters, and there are 46 tiles in the alien (Have you ever count how many pixels I am made of?). 46*3=138, so 3 characters for each colourful square.
Values for Red, Green, Blue. You can use Paint, Photoshop, color selector from developer tools in Firefox, online tools as this one... to see the colours in the image.
Extracting the colour values for each tile, you end up with 46 hexadecimal values (C8E5CC, ECCFA0, D3F4C5, E1CDE7, C9E6D4, E5D2F3, A1A0D4, E8C1EE, CBF3A0, C6EFD2, A0D0E1....)

But those numbers mean nothing :/ That is because (hint 1) there is an offset, I added a number to those values. If you substract 808080 (background color) to each value, you end up with 48654c, 6c4f20, 537445, 614d67, 496654, 655273, 212054, 68416e, 4b7320, 466f52, 205061...
Introducing those codes in xlate, for example, gives you the hidden message.
It is just a bit tedious extracting all the value colors. For substracting the offset you could use Excel, as fR0z3nS0u1 did. m139 used Matlab, mandrill used Python, Tevemadar used c#... because they know how to code. Life is easier if you know how to code.
So the hidden message was:

HeLlO StEaMgIfTeRs! ThAnKs FoR PaRtIcIpAtInG In My PuZzLe
FoRmAt Of ThE AnSwEr: md5(Answer)
QuEsTiOn: WhO CrEaTeD ThE 1st SpAcE InVaDeRs?

You can find the answer in Wikipedia and it is 'Tomohiro Nishikado'. Now you need to calculate the md5 of 'Tomohiro Nishikado'. In internet there are hundreds of webs that are willing to do that for you. For example this one. The web will say MD5 hash for Tomohiro Nishikado is : 8f94f572a4fccbc2efdae5949787f2ec, that is the answer for the puzzle.

I'm so impressed with the SGers who solved this :D

I'm so stupid.

Not my cup of tea, but fantastic puzzle nonetheless. Congratulations to all solvers.

Hmm. Seems the problem was that I had the completely wrong idea about what you meant by "offset". I was working on altering the colors themselves in an attempt to get something to show up instead of screwing around with their codes. Ah well.

I got the colorcode idea pretty quick, but couldn't figure the offset.
Before the 138 hint I dabbled around with an online piano tool for a while to see if cedeceae...etc was a song from Oz :P
It would have been nice if the whole Dorothy and Brick Road theme was kept, I wasn't expecting the space invaders to poke their big blocky heads in again ;)
