Ciroip - one suggestion to you as a user - and I have provided feedback earlier to you also and kudos .....

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.
(remember when I amongst others nixed your Nixie look theme )

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.

This is the single most important factor I believe in why Flip clock was so popular - there are quite a few alarm clocks and alarm clocks by itself is nothing to rave about - but Flip clock was different because of its well designed interface and usage and well thought our design and integration of LED, screen, power usage etc.

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.

Just my appreciation and motivation to push you to more fruitful purposes.
Please don't take it any other way.
