I turned the velocity program into some fun bouncy program
Attached is a screenshot, SVELDRAW (source), and BOUNCE (executable). Press [CLEAR] to exit, [DEL] to reset the velocity, and arrow keys to move the ball.

That sucks. Oh well, teachers are hardly ever appreciating or even acknowledging calculator program.

Well, I showed this program to my science teacher, and he really liked it (both the program and that I'm interested in physics.)

I had countless problems getting it work (especially if I moved up or left or stood still the circle changed into this huge X thing :O) but I finally got it working! (Took a few periods in school tho )

Ok, I am learning Axe! Yay! <insert applause here>
My program lets you use the arrow keys to move a circle around the screen and change its velocity!!!
Added a cool feature!
The circle gets larger the faster it's going!
It's still a bit buggy, but here it is!

At the end, the circle stops instantly. Do this with [DEL]. [CLEAR] exits the program.
Attached : SVELDRAW is the source, and VELOCITY is the compiled program.

You said you had a game idea; what's your game idea?

Just added a zip file to first post that contains install batch file and source. Also I added 3 more commands. (This is a legal double post since you're allowed to post again after an hour if it's a project update.)

I just made a library for Python 2.7 that allows you to easily create IRC bots.
Here is the source code:
import socket
import string
import time
s = socket.socket(AF_INET, SOCK_STREAM)

def connect(server, port=6667):
    s.connect((server, 6667))

def ready():
    x = s.recv(2048)
    if "376" in x:
        return True
    else:
        return False

def register(nick):
    s.send("NICK %s\r\n" % nick)
    s.send("USER  %s 8 *  : %s\r\n" % (nick, nick))

def join(channel):
    s.send("JOIN %s\r\n" % channel)

def send_msg(reciever, message):
    s.send("PRIVMSG %s :%s" % (reciever, message))

def send_raw(data):
    s.send(data)

def recieve():
    x = s.recv(2048)
    if x != "":
        return x

def username():
    x = s.recv(2048)
    return x.split("!")[0].strip(":")

def hostmask():
    return x.split("!")[1].split(" ")[0]

def message(message):
    x = s.recv(2048)
    msg = x.rpartition("PRIVMSG %s :" % (channel))
    return msg

def format_recv():
    return "<%s> %s" % (username(), message())

def timestamp():
    return "%s:%s:%s" % (time.localtime()[3], time.localtime()[4], time.localtime()[5])

def op(channel, reciever):
    s.send("MODE %s +o %s\r\n" % (channel, reciever))

def deop(channel, reciever):
    s.send("MODE %s -o %s\r\n" % (channel, reciever))

def voice(channel, reciever):
    s.send("MODE %s +v %s\r\n" % (channel, reciever))

def devoice(channel, reciever):
    s.send("MODE %s -v %s\r\n" % (channel, reciever))

def ban(channel, reciever):
    s.send("MODE %s +b %s!*@*\r\n" % (channel, reciever))

def kick(channel, nick, reason=None):
    s.send("KICK %s %s %s\r\n" % (channel, nick, reason))

def data_present(check):
    x = s.recv(2048)
    if check in x:
        return True
    else:
        return False

def nick(nick):
    s.send("NICK %s")

def disconnect(reason="Disconnected."):
    s.send("QUIT :%s" % reason)
    s.close()

if "PING" in s.recv(2048):
    ping = s.recv.rstrip()
    ping = split(ping)
    s.send("PONG %s" % ping[1])
Here's all the commands you can currently use:

connect(server) - Connects to the IRC server.
ready() - Returns true if the end of the MOTD is reached.
register(nick) - Registers with the nick.
join(channel) - Joins the channel.
send_msg(reciever, message) - Sends a message to reciever.
send_raw(data) - Sends raw IRC data to the server.
recieve() - Returns the IRC data recieved if it is not empty.
username() - Returns the username of the last message sent.
hostmask() - Returns the hostmask of the last message sent.
message() - Returns the last message sent.
format_recv() - Returns the last message sent like you would see it in an IRC client.
timestamp() - Returns the current time as a string.
op(channel, reciever) - Ops the reciever.
deop(channel, reciever) - Deops the reciever.
voice(channel, reciever) - Gives the reciever voice.
devoice(channel, reciever) - Removes voice from the reciever.
ban(channel, reciever) - Bans the reciever.
kick(channel, reciever[, reason]) Kicks the reciever.
disconnect([reason]) - Disconnects from IRC.
nick(new_nick) - Changes your bot's nick.
data_present(check) - Returns true if <check> is in the reciving IRC data.

It also includes a ping responder, so your bot should never time out.

Soon, I'll attach the .py file and an installer batch file.
Yay! Download the install.zip, unzip it, run install.bat, and yay!

Bug reports and suggestions welcome!

Hiya! I also own an Nspire (the Touchpad non-CX one)!

I'm actually now looking at the TI-66 which is available on eBay with a "Buy it now" price.
