While working on Rush Hour, I have developed a variety of miscellaneous/semi-useful games and utilities in Lua for the Nspire. Here you go:

Flashlight

Designed mainly for those with a CX (I don't believe touchpads or clickpads have backlights), this flashlight features a blank LCD! But can also transform into different colors and contains a strobe function! Try holding random color while doing strobe. IT'S CRAZY! I don't know if this would damage your screen.

Controls-
 0-9 - Choose color
 Tab - Random Color
 Enter - Toggle Strobe
 
Mempi
 
This is based off of the 84 application that allows you to memorize digits of pi on the go. Contains 1000 digits of pi for your memorizing pleasure. However, as a bonus three other irrational numbers were included with 1000 digits, being e, root2, and phi.

Controls-
 0-9 - Input numbers
 Enter - Restart
 Tab - Switch irrational number

Strategy Steps

Taken from a minigame on Wii Party, it has to be the cream of the crop of minigames. Although less fun in singleplayer, you choose either 1,3, or 5 to go the amount of steps. The catch is that if someone else chooses that same number, neither of you can go. First to reach the end wins!

Controls-
 1,3,5 - Choose how many steps
 Enter - Hide/Reveal Signs
 Tab - Restart
 
Source is included.
Sorry, no screenies. Student Software decided to screw me this time.

Suggestions welcome!
Hope you enjoy these three somewhat useful/fun programs!

I think there already is a version for the 84, but I'm not sure what language it's from. That was where I got the inspiration to write this version.

Uh yeah, that's pretty off topic...

But anyways - cyanophycean was a SCRIPPS National Spelling Bee Spell Bowl word that one girl missed maybe three or four years back. She mispelled it cyanophytion or something. Anyways, I like that word. 314 does stand for pi. Now you know.

Oh yeah, cyanophycean means blue green algae

What exactly did it have to do with graphing?
Inequalities?
Conics?

Try to explain what graphing program it is and what it does, even if it's kinda hard to explain. Just give us something more specific than graphing. 

If you're trying a Lua version of whatever it is, I could help. 

That is a very interesting story. 16 years afterwards! 

  There's already a clone... I should check TI Planet for duplicates, but I don't really know french...

Wow, I just checked TI Planet, there are so many programs for the Nspire! I need to go through those...

But anyways, here is a first playable version with 51 levels (I lied previously). The last 9 are dummy levels, but I'll fill them in.

To do:
 -Sprites!
 -Level Editor!

Two Screenies

Enjoy!

This is a pretty interesting improvement, but I'm not sure if I'll use it.

Does this mean you can actually get a clock on the Nspire? That would actually be pretty useful.

Great job to ExtendeD once again!
