How to stack your chips ... Who knew there was a method to it?

I've always wondered how a player determines the method for stacking his/her chips. It seems to be an imperfect science.  Some players are messy w/ no rhyme or reason.  Some players are clearly anal and have all their stacks the same  height and are color coordinated. After scrapeing the web, I've found some common tendencies.

• Stacks of 20 chips are frequently used.
• These stacks of 20 are then placed in rows to form a pyramid, up to 5 wide (see below).

• Keep higher denominations in the FRONT of your stack, in plain sight.  Placing them in the back can be deceiving to another player making bets based on your stack size.  They have a right to know how many chips you have.
• When you have enough chips, most players 'color up'.  This the term is used when you have a large number of chips and want to consolidate them to a higher denomination of chip.  For example, you have 100 $10 chips.  You can 'color up' to have 10 $100 chips instead.
• I have no opinion on this yet, but most internet comments infer that 'tight' players tend to stack their chips more neatly than 'loose' players.  I'm not prepared to let this solely decide how to play an opponent, but it's something to note.

Of course, who gives a crap if you only play online.
