This is a little program which takes a string and creates an image, usually repetitive or pattern-like, based off of the string, use the same string and you get the same picture every time, any changes to the string could bring up an entirely different image however

Here's the pastebin:

Here's an example image (this is "hello")

Spoiler

Usage is: (visual is whatever you called the program)

visual <data>

example:

visual hello

If you want any other examples of strings I will be happy to post them here, or give examples of cool strings.
This was just a little test project of mine to see if I could visualize data, I might be taking this further to make some sort of game, I'll see what I can do. Either way, feel free to use the code for this in whatever you want, just thought I would share this

very cool, have you got a image reader for it so it can be converted back into a string?

That would be interesting

[billysback]

you mean take any image and turn it into a string?
hmmmm.... not really sure that would work as characters share colours...

I've seen code like this very often in your programs:

while index > 16 do index = index - 16 end

Do you know about the modulo operator?

index = (index-1)%16+1

It's equivalent in length in this particular case (whilst modulo is more efficient). But in the case of your encryption program you posted once, it would've made stuff a hell of a lot simpler.

There's more stuff like that, but I shouldn't criticize a published program. I just wanted to make sure that you know modular math.

I'm not sure about the purpose of this program, but it looks funny.

no... I'm presuming it's the "%", in what way does it work?
n-1%17 returns a value less than 17 excluding 17 in a way that is similar or the same way to reducing it by that amount each time?


and its not exactly meant to have a "purpose" other than to look nice

This is sweet. Great job.
EDIT: when i try to run this, it crashes the computer.

Actually, it just gives you the remainder of the division between the first and the second number. Thus:

11%4 == 3
17%5 == 2
(18-1)%17+1 == 2
