Cairo (CNN) -- Outside Egypt's top court in Cairo, protest leader Hussein Abdel Rahman wears a sash around his collared shirt emblazoned with a zucchini. The judiciary, he says, has transformed into what the green vegetable means in colloquial language: corruption, nepotism, favoritism. 

An editorial cartoon in a Cairo daily sums up Egypt's state of affairs: a scribbled mess of spirals. 

And the presidential election this weekend, once hailed as Egypt's big step toward democracy, is now satirized in an online mock-up of a video game pitting a bare-chested Ahmed Shafik, the last prime minister under ousted President Hosni Mubarak, against the bearded Mohamed Morsi of the Muslim Brotherhood. 

The runoff vote is taking place after the Supreme Constitutional Court declared the parliament invalid and triggered renewed chaos over the country's leadership. 

The ruling dealt a blow to the Muslim Brotherhood, which dominated parliament, and was victory for supporters of Shafik, the focus of protesters' derision for his ties to the deposed dictator. 

Anger festered Friday among those who feared that a hard-won revolution was fast unraveling; that little had changed. 

Rankled revolutionaries felt left out in the cold on a hot June day. 

The dissolution of parliament gives the Supreme Council of the Armed Forces, or SCAF, full legislative and executive power alongside, it appears, a friendly judiciary. 

"SCAF has been suppressing our protests, suppressing the youth movements on the ground," said Wisam Mohamed. "They have been arresting thousands of us." 

Ahmed Maher, a founder of the April 6 Youth Movement, which played a prominent role in last year's Tahrir Square uprising, called the ruling "provocative."
