The Egyptian change in government was not simple and required much work by its populace in order to facilitate the change. Which really seemed to ignite the protests was shutting down the internet in Egypt, then the power. This may seem to shut off all lines for the protesters to communicate, however the protesters made use of modern technology in order to continue their protests and reach the outside world.
First off, the protests made up of Bluetooth and Ethernet switches, connected to the internet through Satellite internet, in order to stay connected to the outside world. The government shut down all land based internet, leaving only those who had Satellite. Those people "shared the love" by giving it to others, making their own intranet, connected to the internet.
Secondly the protesters made use of their cell phones as video cameras in order to impart the horrific things that was occurring in their country. In contrast to the videos and images pouring out of Libya however, there are rather benign. Never the less, images of Mubarks security forces running over protests by the dozen are quite shocking, and no doubt fueled support for their protest outside of the country, and inside of Egypt, too.
Lastly the Revolution used social networking sites such as Facebook, Reddit, and Youtube in order to spread their words. Facebook was used in order to organize the protests (Although in later days it was no longer needed to organize anything, for they occurred everywhere at all times). Youtube was used in order to host the videos, while sites like reddit were used to spread word of the atrocities far faster the conventional news sources so much as knew of them.
Here is a graphic displaying more tools the Egyptians used in order to protest. Seeing as I do not know Arabic, I will attempt to expand on their usefulness.
Hoodie, goggles, and Gloves: they serves a double purpose, for protection. They prevent damage from light projectiles, pepper spray, and broken glass, all things likely to be found in major protests and riots. They also serve to mask the identity of the protester, so that one can protest with impunity.
Shoes: Protect against broken glass and whatnot. Doesn't mask your identity, though.
Pot Lid: I makeshift shield, for when police shoot mild projectiles (Sandbags, paint-balls, pepper-balls), or beat them.
Spraycan: To spread the word, or to bank out the president's face on posters.
Singular Rose: To deliver to the funeral of the man you murdered, in order to creative a name and symbol of yourself. Staple of detective novels.
Trashbag(?): Te clean up the city and dump it on police's head, I'd assume.
