The only must-have is virality - the ability to go viral.

<r>Please no cases! R-pi is for kids to handle, empathise with, break and learn to solder, seek the physics inside components and learn the scale jumps between the chip and the circuit board and the web as steps to those between neurons and the zoosphere, touch components and dream about how to impr...

<t>Am I the only fan here of Wolfram Alpha the maths search engine?<br/> It's online, it's free, it's backed by Mathematica, and has virtually every math algorithm ready coded. The creators are sitting on and using constructively several billion, so don't need to charge. When Stephen Wolfram wrote A...

<t>Hi sightlight In the 1970's many kids learnt programming from typing in games from magazines, then debugging. R-pi will be used in places where the teaching is zilch, the net is down or hasn't reached, and an able youngster has cobbled a system together, or perhaps in a hole in the wall situation...

<t>A first ten programs, where fleshing out a skeleton or just typing in the code and debugging might spark an interest.<br/> <br/> Hello World in language of choice, with two sentence follow up.<br/> Eliza<br/> Worddrop<br/> Tit for tat, with options like defaulting, generous, generous with enigma,...

Can we build a list of topics, with newbie/inter/journeyman examples, that might be in real computer science?
And use RP to demonstrate them, for exploring, extending, enthusing others?
Perhaps like what Wolfram Demonstrations has done/is doing for math.

Would a list of Hello World's be useful to give us a flavour of each language?
And maybe a simple sample of Eliza?
