Хорошее предложение…
я, кстати, по этому пути тоже двигаться пытался…но это было 4 года назад. я тогда только начинал JS постигать… получилось не очень, да и шаблоны тогда удовлетворили вполне.
Сейчас, надеюсь, будет попроще.
Есть какие то ссылочки на тексты или прототипы …подглядеть, что бы понять куда двигаться?
а я пока пойду свои скрипты старые подниму.
что то в этом духе?
