While your playing around with C / SDL / Pygame etc is very good and that sure helps, as a selfish user, I would like to see you use your time and skills to creating new apps and not remake Flipclock too much again - as that already fulfills most of the purposes for most of the users.
What I see lacking in many other apps is a good design concept like your Flip clock has and good integration and mobile usage thoughts going into it.
So as a user who cant do anything by himself, I would rather goad you guys along to put your skills to some more useful application designing.
Please don't take it any other way.
