 * Prime Competition — halaman masuk portal siswa.

 * Terang dan ceria untuk anak SD sampai SMA: langit bergradasi lembut,
 * gelembung warna dan ikon pelajaran yang melayang pelan, kartu putih
 * yang muncul dengan pantulan kecil. Formulirnya sendiri tetap tenang
 * dan besar — yang bergerak hanya hiasan di belakangnya. Semua gerak
 * berhenti bila perangkat meminta "kurangi gerakan".
