This is original post, I have updated instructions here that work better with OSX Lion.
This is really cool!
I found basic info about this here:
http://hints.macworld.com/article.php?story=20091221173111783
How I made this work to lock/unlock & displaysleep/wake my computer when I am (or my phone is, actually) near it:
The way I improved upon the above link is by making my computer display actually go to sleep, turn off, this saves power and makes it last longer. The same as pushing "shift-control-eject" at the same time.
Step 1:
Do this:
http://kprops.blogspot.com/2011/07/sleep-display-instantly-hack-found-not.html
This creates a unix executable that will sleep the display instantly when run,
save it in Applications folder
Then in system preferences, "security" check "require password....blah blah blah" to "immediately"
then file menu, new password item:
Keychain item name and account name, set to "myPass"
Password: set to the password you use to log onto your computer.
This stores your password in a secure place that we can later access via script.
Step 3:
Download the opensource free file "Proximity 1.5.zip":
from this page
http://code.google.com/p/reduxcomputing-proximity/downloads/detail?name=Proximity%201.5.zip&can=2&q=
(short link direct to file: http://goo.gl/9YATT)
extract it to Applications folder.
(read about it below before you install cause it's smart to do)
http://code.google.com/p/reduxcomputing-proximity/
Step 4:
Write 1 applescript in scriptwriter, named as below:
SleepDisplay.scpt
===========
on run
tell application "Terminal"
do script "/Applications/SleepDisplay"
end tell
end run
==========(below also)
This script just calls the executable you made in Step 1
Save it in the Applications folder
SleepWake.scpt
==========
on run
tell application "Keychain Scripting"
set thePW to the password of first key of current keychain whose name is "myPass"
tell application "System Events"
tell application process "loginwindow"
keystroke 125
delay 1
keystroke thePW
delay 0.2
keystroke return
end tell
end tell
end tell
tell application "Terminal" to quit
end run

Save it in the Applications folder
NOTE: Do ONLY step 5a or 5b, 5a for pre-LION, 5b for Lion
(since Apple removed Keychain Scripting app in Lion)
There is another problem with Lion. 5b script below only logs you in, it doesn't actually nudge the display awake. Once you sit down you have to hit any key (i use the down button) to wake up the display, but at least you don't have to enter your password.
Step 5a: (for pre "OSX Lion")
SleepWake.scpt
==========
on run
tell application "Keychain Scripting"
set thePW to the password of first key of current keychain whose name is "myPass"
tell application "System Events"
tell application process "loginwindow"
keystroke 125
delay 1
keystroke thePW
delay 0.2
keystroke return
end tell
end tell
end tell
tell application "Terminal" to quit
end run
=============== (below also)
Save it in the Applications folder
Step 5B (for Lion)
SleepWake.scpt
===============
on run
Step 5B (for Lion)
SleepWake.scpt
===============
on run
set thePW to ""
set label to "myPass" -- use the name of the password you made above
set thePW to do shell script "security 2>&1 >/dev/null find-generic-password -gl " & label
-- following several lines from: http://macscripter.net/viewtopic.php?id=36818
set oldelim to text item delimiters
set text item delimiters to "\""
set tlst to every text item of thePW
set thePW to item 2 of tlst
set text item delimiters to "\\"
set tlst to every text item of thePW
set thePW to item 1 of tlst
set text item delimiters to oldelim
-- this will now work if your password contains problematic characters or is not 7 bit ASCII
-- see this : http://www.j-schell.de/node/401
tell application "System Events"
tell application process "loginwindow"
keystroke 125
delay 1
keystroke thePW
delay 0.2
keystroke return
end tell
end tell
tell application "Terminal" to quit
end run
=============== (below also)
Save it in the Applications folder
Step 6:
open Proximity app you just downloaded
(icon will be in upper right of screen)
pair your phone with your computer by using the "change device" button
set "Out of Range Script" to:
/Applications/SleepDisplay.scpt
(the first script you created above)
hit "test"
Screen should sleep, log back in
set "In Range Script" to:
/Applications/SleepWake.scpt
(the second script you created above)
hit "test"
You may get several repeated security warnings asking you to allow keychain access etc by several programs, just enter your password whenever it asks and click "allow always" or "allow" if always isnt available. this is giving the app proximity and the script permission to look up your password that you securely stored in keychain, so you don't have to store your password in plain text format.
Step 7: (important!)
Once it is working and tested and you are happy, open the script "SleepWake.scpt" in AppleScriptEditor, and re-save it by using the "Save As..." File command and check the option box for "Run Only" this will prevent someone from opening it up in script editor and running it and then viewing your password in the script results. Name it the same name and overwrite the original file.
Enjoy!
Leave bluetooth active on your phone. When you walk away from your computer with your phone in your pocket the display/s will sleep and lock, requiring a password to login, (in case you come back without your phone)
when you walk back with your phone in your pocket the screen will automatically unlock and light up.
You could also tell the wake up script to play a sound file that says hello to you, and the sleep script to say goodbye, use text to voice engines etc, etc... :)
set label to "myPass" -- use the name of the password you made above
set thePW to do shell script "security 2>&1 >/dev/null find-generic-password -gl " & label
