i don't have one yet, i don't even have an arduino, but i would love to try it, just to lear some about the communication between software and hardware.
if i had one, i would use this one: http://www.adafruit.com/products/250 because it is 128*64 (like yours, so this won't be a problem i think) and it's quite cheap...

That surely is awesome. Change the color depending on the level you're in :D Blue for water levels, orange for lava levels, white for snowlevels. Flickery colors for epileptic side-effects.
If you like my work: why not give me an internet?

how much CPU speed will it heave?
My projects
 - The Lost Survivors (Unreal Engine) ACTIVE [GameCommandoSquad main project]
 - Oxo, with single-calc multiplayer and AI (axe) RELEASED (screenshot) (topic)
 - An android version of oxo (java)  ACTIVE
 - A 3D collision detection library (axe) RELEASED! (topic)(screenshot)(more recent screenshot)(screenshot of it being used in a tilemapper)
Spoiler For inactive:
- A first person shooter with a polygon-based 3d engine. (z80, will probably be recoded in axe using GLib) ON HOLD (screenshot)
 - A java MORPG. (pc) DEEP COMA(read more)(screenshot)

Haha, that's very cool. It's very reminiscent of the music produced from computers internal speakers. This was in older computer games or computers with crappy sound boards back in the day. :D

How do you even make music for this?

Some code, bunch of numbers and standard I/O functions :)

Actually, switch a pin with a speaker connected to it on and off pretty fast.

A NE555 osc connected to the pwm output with a lowpassfilter works as well.

Analog electronics :) The arduino has PWM(pulse width modulation) right? Attach a lowpassfilter(look it up) to fill up the gaps between pulses to make a constant voltage output. Feed this signal called CV(controll voltage) into a NE555 chip oscilator circuit to produce a squarewave. You can also attach other types of oscillators.

Sounds nice. Or else I heard you can use the Commodore 64 sound chip.
