Here are some screens shots from the TI-83. We made them with the help of a handy Graph link and some randow browsing of Kyle's calculator!

All bow before the math monkey!
The [Angle] menu	Calculus functions for graphing
Kyle threaten to kill me if I deleted his games!	The result of boredom in math class. Made with the draw pixal function
The [Draw] menu	A sample graph with the default settings
Checking your memory	AAHH! NO, I'll be good. Please, NO!
Look at the size of Kyle's program's folder!	Need we say more
Changing [Mode]s	The [Stat] Plot menu
Setting up a Stat Plot	The [Test] menu
[Window] settings, I don't know why	The [Y=] menu
