Renk Animasyonu ve Fizik; Saf JavaScript, 457 (335) bayt
Bu forumdaki ilk yazım; Bu kodu yaptım ve geriye göndermek için bu konuyu içeri göndermek için buldum.
HTML’de kapsüllenmiş, bir html dosyasına kopyalanıp yapıştırılmaya hazır kod:

Piksel mükemmel çarpışmalara, doğru kuadratik fiziğe ve tamamen renkli bağımsız çevrimdışı Javascript koduna değinen, 457 byte değerinde pürüzsüz renkli animasyonlara sahiptir;

Ayrıca DEFLATE gibi bir sıkıştırma sistemi kullanmak hile yapıyor mu?
Aşağıda, kodun DEFLATEd sürümü için ASCII85 kodu verilmiştir:
Bu arada, sıkıştırılmış toplam 335 bayttır.
