When you design a Fun@work environment for your intranet remember that different people have differing views as to what constitutes fun. So mix several ingredients together, then you can please all of the people all of the time! The experiment that I implemented over two years in a large corporate financial group, used several successful key principles:

	Include a fun area that creates Laughter. University research, testing subjects both before and after a thorough laugh session, have found that laughing lowers the blood pressure, releases natural pain killers (endorphins), and boosts the immune system. Not bad for having fun! Staff sickness will drop. And in a survey of 102 staff I conducted only 2 did not think humour affected customer contact.
	Don't let the brain drain away. Research has shown that adult creativity is a small fraction of childish creativity. We tend to use certain patterns exclusively and it reinforces neural pathways. We stop thinking properly. Make sure you exercise those pathways by including a section with mental puzzles. Trick staff into making wrong assumptions, incorrect perceptions and hid solutions mischeaviously. Eventually they will start to recognise the tricks and outwit the puzzlers. Work issues will start to be less problematic. "
	Include a section for those who like facts, articles, profound quotes, anything that looks at things from a new perspective. Consider the advantages of failure in a positive light. You will motivate people.
	Imagine you've been working hard all day. Your energy level has dropped to the floor and is scraping the ground behind you. All you can think of is going home, plopping down in your easy chair and "vegging" out in front of the TV, preferably in a darkened room with a drink. But you still have several hours to go! What the heck can you do? Look for Inspiration. Include a section using simple metaphorical stories that tap into the sub-conscious, break the spell, and re-energise staff.
	Personal issues at work can grow from mole hills to mountains. Problems with the boss, your colleagues, your environment, your reward system. People need to let off steam to allow them to function properly. Introducing an independent Corporate Fool, an on-line agony aunt that helps people to release the stress. And it can offer an independent perspective on corporate life, breaking through the spin that companies start to believe about themselves.
	Include material that supports your assumption that fun improves productivity in the workplace. This is the metrics area for the sceptical. Show balanced feedback, daily statistics and trends and rationale for your case. Open the debate treat all perspectives equally.
	Make sure you stay connected to your audience. Act as a resources match-maker connecting people with similar problems and issues from across the organisation. Circles of excellence if you will.
