under that click on lesson1 link. click on any particular letter(scrolling under the page). Now you will see a letter is smoothly generated. What kind of software I require to make that? It seems that flash is not adequate for that(it is generating in a discrete way). Is there any readymade software available for that? also if I have the ttf file, is it possible to generate that effect? Please help.I am stuck.
