Create a web page that utilizes an HTML form to gather information from the viewer, and pass this information to a page that does something with this information. You can use your imagination on what might be done with the information, but here are some possible ideas:
All of these things are (I think) possible with PHP. Obviously, some would be a bit more difficult than others. But it is time to start thinking about the larger possibililites for the technologies we have been learning. You now have a basic foundation for taking these technologies further. All you need to do is to start thinking larger, then dig in and figure out how. You have most of the tools you need, and what you don't have, you can figure out as you go.
Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance that they were present, or to have an effect, at a location other than their true location.

The following quotes were copied from the website: http://www.artpool.hu/2004/telematic.html. There are lots of other interesting things to consider on this site.
...The creative use of networks makes them organisms. The work is never in a state of completion, how could it be so? Telematique is a decentralising medium; its metaphor is that of a web or net in which there is no centre, or hierarchy, no top nor bottom. It breaks the boundaries not only of the insular individual but of institutions, territories and time zones. To engage in telematic communication is to be once everywhere and nowhere. In this it is subversive. It subverts the idea of authorship bound up within the solitary individual. It subverts the idea of individual ownership of the works of imagination. It replaces the bricks and mortar of institutions of culture and learning with an invisible college and a floating museum the reach of which is always expanding to include new possibilities of mind and new intimations of reality...
...But these new insights and this new technologies of cognition, perception and communication are not merely additions to the repetoire of human behaviour, they are actually transforming human behaviour in important ways. The impact, for example, of telepresence and interaction in virtual reality have incalculable implications for the way we live, just as hypermedia and multimedia systems, as they develop, will have immense implications for the way we navigate information and generate knowledge. It is not simply that in the computer, the artist has found new tools, it is that we now inhabit a new environment, an electronic dataspace. The task of art throughout the 20th century has been to make the invisible visible. Now we have the means to more fully realise that ambition. Rather than denying the spiritual dimensions of art, computer-mediated systems subtly enable us to extend those dimensions.Telematic technology is finally a 'spiritual' technology, its domain is that of human consciousness. Connectivity through the electronic networks induces telenoia, a life-affirming sense of mind-at-large. Pre-telematic society induced only paranoia, the Self imprisoned in the mind...
...In telematic art, meaning is not created by the artist, distributed through the network, and received by the observer. Meaning is the product of interaction between the observer and the system, the content of which is in a state of flux, of endless change and transformation...
"...cyberculture has become synonymous with the so-called 'new edge' of the subcultural avant-garde; a bricolage of technoculture, neo-'60s psychedelia, transcendentalism, designer 'smart' drugs, modern primitivism and 'strechnology' (the do-it-yourself street ethic of finding a use for things). In a much more specialised sense, cyberculture is associated with cyberpunk. Cyberpunk is equally difficult to adequately define. However, most accounts tend to portray it as the wired successor of the punk sensibility of the late 1970s... Cyberpunk is a lifestyle, a way of living in a telematic society, as well as an attitude towards it. It is a hybrid blend of info-tech obsession, Situationist politics, poststructuralist savvy and liberterian utopics." Darren Tofts, Memory Trade...
