That image reminds me of TLOZ's triforce.

true, or a RclPic or a sprite for Axe, but thats not calc generated, its technically done by you and just shown by the calc.

Couldn't your Axe program be a lot faster if you only moved the buffer to the screen after all the points are plotted on the buffer? That way you don't get the LCD slowdown issue. But those are cool :) There is also a example on TIBD by Weregoose here.

Wow, nice. I don't get how those Sierpinski generators work. At all :(

I remember the example SIerpinski program in my TI-83+ manual (the manual that had like 900 pages). It looked quite cool.

Btw how fast would be the Axe one if you did not update the LCD every pixel?

Okay, So I learned about the Sierpinski triangle in my 82 book. Anyway, it is created one of two ways.  The way used here is called the chaos game.  There is another one called Rule 90.

I dont think an Axe version could be created, since the basic one uses heavy floating point arithmetic :(

DJ:  did you get the manual with your calc, or did you print it off?

The "Handbook" that came with my calc had the generator as an example program. I'm assuming that's the "User's Guide", because I checked the online manual and it's totally different.

???  I made one in Axe...
you don't technically need the floating point since it really just assigning every pixel a decimal between 0 and 1, just replace the 1s and 0s with 0s and 96s or 0s and 64s and your all set.  ;)

Damn, Deep Thought thats like the 5th time today!  :P
anyway, my "User Guide" isn't near 300 pages.

Ah, I'd forgotten about cellular automata. I just happen to have an Axe program somewhere in my personal archives that can draw any 1D CA, including rule 90, in under two seconds.

And yes, I know it uses an incredibly inefficient routine. It was my first Axe program.

It came with my 83+. It's pretty much the same as the guidebook PDF on TI website
