(the pun on the pop artist's name is intentional, but regrettable) was made for GloriousTrainwreck.com 's 2 hour Klik of the Month Klub game jam. So in 2 hours I took a borrowed Life engine and made a game out of it where you're a little happyface square who has to run around a Life field, but there's a chaos-provoking ghost who burps out extra cells to stop Life from setting into its repeating blinker ways.

Well, I don't have a "score box" exactly, I just print the score every time in the draw routine.

The somewhat tricky thing about using text in processing is setting up a font. There are a few steps:
1. while you're developing your program, add the font it
2. a line of code that says you're using this font
3. a line of code to print the text

These instructions apply at least to Windows:
A. go to the Tools dropdown menu and hit "Create font..."
B. pick a font, one that looks good to you. If you know the Size you're going to want to use the font at already, select it. Otherwise keep the default of 48.
C. Copy the "filename" showing there. In my case, it's "Arial-Black-48" and there's a ".vlw" after it. Then hit OK

So in the setup() of your program, do something like this:
 textFont(loadFont("Arial-Black-48"),20);
that tells it to load that font file (loadFont - you want to do that once, not over and over), and then textFont says start using the font that the loadFont returned.

Once you've done that-- if your score is in a variable called currentScore, and you want it near the top left of the game, something like
text(currentScore,10,20);
where 10 and 20 are the x and y of where it should go.

If it needs to be in a box, just draw a box before you draw the score.
