Nyancat rendered locally as a character device.

You will need to install the needed tools and libraries to build. First build the module (these 2 dependencies are needed on ubuntu/debian):

sudo apt-get install linux-headers-$(uname -r) build-essential

Compile the module:

make

Copy the udev rule to the correct place (this creates the device node for you upon module insertion):

sudo cp etc/udev/rules.d/10-nyancat.rules /etc/udev/rules.d/10-nyancat.rules

Insert the compiled module:

sudo insmod nyancat_cdev_module.ko

cat the character device:

cat /dev/nyancat

Use cat and echo to view and modify the 2 parameterst that control the output (90 ms and xterm are the defaults):

> cat /proc/nyancat/delay_in_ms
90
> cat /proc/nyancat/term_type
xterm
> echo 250 > /proc/nyancat/delay_in_ms
> echo vt220 > /proc/nyancat/term_type

Acceptable values for term_type are: xterm, linux, vt220, fallback, rxvt, and default.
