https://www.ethereum.org/greeter tutorial greeter contract created. By execusing the following code on ethereum console, you will see 'Hello world from 0804 Smart Contract Japan meeting!'

	// Greeter contract on main net
	> var address = '0x7717efe25b65c8c0fcb97a170b086c17b025a1e1'
	> var abi = [{ constant: false, inputs: [ ], name: 'kill', outputs: [ ], type: 'function' }, { constant: true, inputs: [ ], name: 'greet', outputs: [{ name: '', type: 'string' } ], type: 'function' }, { inputs: [{ name: '_greeting', type: 'string' } ], type: 'constructor' } ]
	// call the greeter contract
	> var greeterFactory = eth.contract(abi)
	// contract address
	> var greeterInstance = greeterFactory.at('0x7717efe25b65c8c0fcb97a170b086c17b025a1e1')
