Sometimes on the internet you find custom software that are free to download, that look like they would be a laugh for a maximum or a day or two.
The people over at FAT Lab have created a piece of software that runs in the background to turn all your typing programs (Word, Pages, Internet browsers...etc) to have the sounds of a typewriter with whatever ever you type. The sounds include; letter keys, spacebar, backspace, carriage return and scroll up and down.
The software is a simple download and procedure to install the software to run on your machine instantly for endless fun...well for maybe a week. At the moment this software only capatable with Mac OS (W'hey!)
