I was practicing writing on Skritter just now, and as I was in the middle of drawing a character I got an email that I went to read.
After I read and dealt with the email, I returned to Skritter and continued exactly where I left off (in the middle of writing 通) . I consider 通 to be an easy character to write, but when I got back to Skritter and looked at the pinyin/English of what I was writing and saw that half of the character had been written , I got the next stoke wrong.
My suggestion is for us to have a "game mode" Skritter , in which sometimes characters are already partially written out and we have to complete them. I think this will force us to think in more then one dimension and will help those who are decent at writing to push characters deeper into our memories and have a clearer recollection of them.
It would kind of be like playing on one of the tough levels of Tetris, where the round starts off with everything in kind of a mess and you have to play your way out of it.
I don't know how pheaseable something like this would be
