Summertime in a busy city. The library is full of people. Students mill about, going from talk, to workshop, to assembly; occasionally taking a break to enjoy a free concert, or simply relax in the company of friends. A familiar exam-term routine? Perhaps; but this isn't Cambridge.

Welcome to 'Acampada Sol'. Since the 15th of May, up to 30,000 protestors have been camping out in this makeshift community in Madrid's pulsating centre, the Puerta del Sol. The 'indignados', or 'angry ones', as they have been dubbed, are outraged at the alleged corruption in Spanish politics and are working towards a future where politicians can be held accountable for their actions and ultimately work with their electorate to better represent their citizens.

Marian Martinez, 23, a journalism student at Madrid's Europea University, has been a member of the so-called '15-M' movement since its inception. She bemoans the fate of her university-educated contemporaries, desperately searching for jobs in a country with a 44% youth unemployment rate and public debt estimated at 488 billion euros. "What's happening in our country isn't fair. We're trying to work for a better world. This is about more than just Spain. This is something beautiful."

Beautifully coordinated, at least. In a country often derided for its less-than-efficient bureaucracy, the city centre camp is a revelation. From the solar panelling to the free wifi available to 'residents', everything that has contributed to the development of the camp infrastructure has been amassed from public donations.

Participants are keen to stress that this is an inclusive movement for change, open to all, and the public have responded generously. The kitchen area is stocked handsomely, and a mountainous stack of toilet roll threatens to topple. Speakers announce that water for cooking is available at one of three food stations, and protestors have even created an orchard in the square's showpiece fountain. Daily assemblies at six in the evening keep participants informed of developments.

Further amenities include a nursery, two so-called 'hospitals', and a children's entertainment zone, highlighting the broad appeal of the protest - people of all ages mix freely and deliver their proposals for the future of the movement.

Indeed, the future is uncertain. The participants have voted to pack up the camp of their own volition this Sunday, having previously defied police orders to leave. Businesses around the square are getting tired of the disruption too. Their windows have been covered with carefully crafted placards displaying slogans such as, 'Spain is not a business, we are not slaves,' and calls for the people of Europe to rise up.

But for a movement which prides itself on working as a team and having no appointed leadership, carrying the current momentum forward may prove a difficult task. For now, Marian is happy to undertake the role of spokesperson to continue raising awareness of the protestors' concerns and imprint a lasting image of this Spanish revolution upon the public consciousness . She is very happy to talk to the media, given that much of what has been reported has been deemed false or inaccurate.

Indeed, the British press has been criticised for jumping to the conclusion that the student population within the camp are solely protesting the tough austerity measures imposed by Prime Minister José Luis Rodríguez Zapatero's PSOE government in an attempt to try and alleviate Spanish economic woes.

Marian is keen to stress that, officially, she and her comrades do not belong to any particular political party or protest group. Rather, they are united in their desire to put an end to the two-party politics Spain has witnessed in modern times. The constant battle between the socialist PSOE and the right-wing Partido Popular (PP) saw Zapatero's socialists suffer dramatic losses in last week's elections winning 28% of the vote in comparison with the victorious PP's 37% share.

However, schisms within the camp may be beginning to show.

Sub-camps advocating  vegetarianism, veganism, feminism, and environmental awareness have been created. While it cannot be denied that the members of these groups demonstrate a predominantly left-wing bias and, as such, share broadly similar political viewpoints, worries are surfacing that the original objective may be lost underneath a plethora of separate anxieties.

Nevertheless, similar occupations have appeared in Barcelona, Seville, Valencia, Bilbao, Zaragoza and Granada and popular support for this reclamation of democracy shows few signs of abating. The 'Spanish Revolution' social networking groups are disseminating the occupants' message of 'Yes we camp', reappropriated from Barack Obama's famous 'Yes we can' .

Marian says that she has had fun participating in the Madrid occupation, getting goosebumps when the participants are rallying in Sol, en masse. But she is quick to reiterate that the protestors have worked hard to get their voices heard. And perhaps the hard work is only just beginning.

If the camp do indeed go ahead with their plans to dismantle their makeshift home, plans past this weekend are sketchy at best. One possible line of attack is to decentralise protesting by creating smaller action teams within each neighbourhood within the city. But some participants hope to continue the occupation to show solidarity with their compatriots in Barcelona who have been the subjects of alleged police violence this weekend.

Even Marian herself is doubtful that this momentum can continue: "Hopefully something bigger will arise from this movement, but, sincerely, at the moment, it's hard to tell. My biggest worry is that all this will end without a future. And we will have accomplished nothing."
