Do you need this design to be on the website?

Yes on the main page. If you have any questions let me know. The basic idea is to allow the user to edit a stroke that was written in the past. The main js script is paper.js.

Okay, I will try to do it in an efficient way.

Zaid, I just wonder why you need to make a drag option to the letter ?
I think clear and update is enough because it's already in the correct sequence.
