Logotron 3000

Code Sharing

I was playing around in Codea tonight and decided to make this simple game logo generator. Feel free to use it however you like. Note that the code is a bit hacked together, as I didn’t really have an idea in mind of what I wanted before starting.

You can customise colour palette and font.

@Simeon - that’s cool :slight_smile:
I can see a use for that if expanded a little - maybe add a degree of randomness, add a background ellipse, export to photo’s / dropbox

@Simeon,

Neat little package - I can see this routine on many future intro pages.

Thanks, I figured it might be helpful for people doing quick prototypes and needing something slightly better looking than plain text.

@Simeon,
Superb?i love the code so much that

i wanna show str without special effect?how to adjust the value of w to make chars’ blank normal?
