A selection of 16 new and notable apps for you today:

Python Bytes – Monty Python Series 1

And now for something completely... Well, yes. This app offers 22 of the best sketches from the first series of Monty Python's Flying Circus, as well as commentaries. Shaking the iPhone brings up another sketch at random, although they can be chosen individually too. There's also a fun "App Signing" feature – Pythons Michael Palin, Terry Jones and Terry Gilliam will be appearing at Apple's Regent Street store in London on 3 May to scribble their signatures on the screens of fans with the app.

James May's Science Stories

London's Science Museum has a new augmented reality app starring Top Gear co-host James May. Point an Android or iOS device at specific exhibits, and a virtual May pops up to explain them – although the AR markers can be printed out for use at home too.

Klout for iPhone

There's nothing worse than a Klout bore, chuntering on about their social influence score while pleading for +K to boost it. Now there's an app for that, on iPhone. It cleverly displays the user's Klout score as a notification icon on the iPhone homescreen, while providing other alerts about changes.

SnipSnap

I think this may be a US thing for now, but SnipSnap is a very interesting idea. It involves snapping photos of printed coupons – vouchers, ads in magazines and newspapers, and so on – and turning them into a "mobile-optimised offer" to be redeemed by showing your iPhone in a store.
