    What is Pixel Sandbox?                                    Try Pixel Sandbox (beta) at tikolu.net/pixel-sandbox
    
      Pixel Sandbox is an online tool which allows you to create custom patterns and filters on a per-pixel basis.
      This is done by arranging blocks to form a script. The project is still very early in development, and a lot
      of new features are still yet to be added. The goal is for anyone to be able to make their own scripts and
      publish them to the community, which will allow anyone else to use them.
    

    Your feedback is important!

    Feedback:

    - It looks very promising! I would love if there were different types of loops though, other than the right-down
      "for each pixel" loop. Maybe a down-right "for each pixel" loop? How about a "For" loop? And also, a question:
      is there a way I can access any individual pixel I want, and, for example, extract its color?
      Second point - sometimes when I do a calculation I get a number above 100 or below 0, so I can't use it as a
      value for color. Although I can (and do) use if statements to get around that, a "compress" function would be
      nice. And lastly, how do you minimize the "examples" window on the bottom? I want to make my workspace bigger...
      Again, if I didn't make this clear - this is very useful and neat and I could see many potential uses for it,
      It's just that currently the amount of things you can do is quite limited.


    - You can access the colour of a pixel by using the "colour" block (see the filters in the examples for a
      demonstration).
      As for the loops, there is now a for loop available in the list blocks. To "compress" a value, just divide it
      by your maximum possible value, and then multiply it by 100.

   - Cool! But im still confused how to use it though
