Letter M Press is a forthcoming iPad app aimed at recreating the letterpress experience with software. You select and arrange type, put in the proper spacers and roll the ink. You'll be able to save the designs and export out for use in other programs - so it's not a frivolous app, you could actually use the creations elsewhere. According to this Kickstarter they've actually got a good deal of the app itself written but they need more samples of type to use within it. They've met their goal already (congrats!) but with 48 days left to go on their fundraising they could probably raise a good deal more and make the app that much better. It is, without a doubt, a very intriguing undertaking and I look forward to seeing more from it.
