Two By Two by Noice [web]

Release info
------------
Name: Two By Two/Noice
Release Date: 2007-04-08
Code: Andreas Gustafsson aka. Shadow/Noice
Graphics: Sven Ruthner aka. Ptoing


Running the demo
----------------
To run it you will need a TI-83 with ION shell installed
(and nothing else, since it uses almost the entire memory!)
I've also included a TI-83+ version, but it is untested.
Note that the demo will not work under VTI, the
IRQ-grayscale routines are not compatible with the emulator.


Technical info
--------------
Grayscale twister:
This twistbar is running in IRQ-driven grayscale mode which
you probably won't see much TI-effecs doing, since the grayscale
routines actually steals 60-70% of the aleady limited CPU time...

Chunky mode twirl:
This old effect is making a reappearance in the new chunky mode
after which this demo is named. The 2x2 pixel chunky mode has
4 dither-levels and runs in a 64x64 area (32x32 chunky pixels).

Rotozoomer:
Perhaps the first rotozoomer on the TI83! (Yeah, I know EhD had one
on the TI86, but this one has some improvements! :))
It is also running in the 2x2 chunky dithermode and uses a 32x32 picture.

Stretch scroller:
Oldschool stretch scroller with per-character adjustable char-width.
Guess this one is a tribute to my old C64 days! :)


Additional thanks
