Here is a cool NaNoWriMo word meter you can use to keep track of your daily word count. You can set the color of the progress bar. Just plug in how many words you've written so far, how many total you plan to write (50,000 default), choose a color for your progress bar and hit calculate. Then just copy/paste the code where you want the NaNoWriMo word meter to appear! This word meter functions completely independently from this website - it is image-free and script-free.
Example NaNoWriMo Word Meter:
30000 / 50000 words. 60% done!
