Lots of dots 

Dots can help you grasp big numbers.
Here is 10^{0} x 10^{0} = 10^{0} (1 ; one ) dot..
Here are 10^{1} x 10^{1} = 10^{2} (100 ; one hundred ) dots...
Here are 10^{2} x 10^{2} = 10^{4} (10,000 ; ten thousand ) dots... Here are 10^{3} x 10^{3} = 10^{6} (1,000,000 ) one million dots. 
Here is A dot for every second in the day(includes a clock!)
Here is A dot for each day. 
Ideas...
How many yeardots old are you?
How many peopledots are in your building?
How many secondsdots since you last ate?
If you live for 50 more years, how many daydots is that?
You can color and group the dots...
If each dot is a day of your life, you can circle your first year of school, etc...
If each dot is n dollars, show how some budget is spent..
The age distribution of some population...
Graph paper is another way to play these games...

Notes: Do browsers have any difficulty with the `million dots' page? Printers do 300 or 600 dots per inch. So 22 or 90 thousand per in^{2} (single dots separated by single dots). With 8 x 11 = 88 in^{2} paper, thats 2 or 8 million dots. So one could easily do a milliondot sheep of paper.
Doables: A dynamic generation service would be neat. Colors, clumped&scattered, Postscript or image for a million dot sheet of paper.
