My thoughts:
this is getting very collaborative like 21st century interconnected world.

by the way everyone,

i am stuck trying to rectify programming "bug", trying to make the applet remember the  presets_combo drop down list.

I notice the list does not change after the reset button is pressed meaning i want to show the correct "option" dynamically.

My latest xml is here if you want to help remix ;D

YouTube. Was stuck at Portland airport from 11pm to 4am, decided to use the time to make some promotional video on the applets shared during 2010 AAPT Summer Meeting in Portland, Oregon
