Ingozi: Amandla aphantsi, akafumaneki okanye ngamaxesha athile avule navaliwe.
Uhlalutyo lwesizathu:
I-weldment ayicocwanga.
Ukuguquguquka okunganelanga okanye umgangatho ophantsi.
I-weldment ayishushu ngokwaneleyo.
09
I-asymmetry

Iimpawu zokubonakala: i-solder ayidluli phezu kwepadi.
Ukwenzakala: Amandla angonelanga.
Uhlalutyo lwesizathu:
Isoda ayinamanzi amdaka.
Ukuguquguquka okunganelanga okanye umgangatho ophantsi.
Ukufudumeza okungonelanga.
10
Ikhululekile

Iimpawu zenkangeleko: Ucingo okanye icandelo lelothe lingashukunyiswa.
Ingozi: Imbi okanye ayiqhutywanga.

11
Lola

Iimpawu zembonakalo: zibukhali.
Ubungozi: Imbonakalo engalunganga, kulula ukwenza ibhuloho.
Uhlalutyo lwesizathu:
I-flux incinci kwaye ixesha lokufudumeza lide kakhulu.
