Not at all, do you have a link to the project? Thanks anyway, and thanks Mandrill for the comparison, hadn't heard of him before, it is quite impressive.
Well, thanks for the feedback everyone !
I must say making them was not an easy task. Here is the code for the ones interested. @Mr.Fahrenheit, it should work on TI84 just fine I think, but I cannot test it. And it's the same, I did it in math so I could draw during the class!
Basically, there is a pixel-square cursor blinking. You can move it with the arrow keys, and by pressing the alpha-key you are able to switch between the active and inactive state. Active state allows you to draw lines, and erase other when you run over already drawn pixels. It's not a prefect program, but it does what it says 
(You can exit by pressing enter, and it does not clean the screen before and after, so you can save and reuse images)
(I will add the ability to draw dotted lines, to ease dithering a little)
But yeah, this is my tool!
Nice one, techie.
The head reminds me of Jim Murray's style. 
Hey ! Are you related to the guy making the ikaruga remake for calculator ?. These looks very good :)
This is exactly kind of stuff I really like - making with tools you make yourself. Great work.
Her shoulders frowning on the touch is really expressive! Congrets!
Yeah I'm interested in how you painted it as well, and if there is a program for the Ti-84!
Math class is so boring :c
Cool picture too!
How are you able to paint on a calculator without some kind of pointer or pen? This is great, I'd love to see how it works.
