For any high school students here....
You may want to check out the mcluhan multimedia festival (M3F.) It's a national festival that celebrates the new media artwork of Canadian high school students in the categories of animation, desktop publishing, digital photography, fusion (see the website for more information,) illustration, image manipulation, interactive media, sound and video. The works are judged by professionals in the field, so this is a great opportunity to get some feedback.
Even if you don't win, it's a great opportunity for exposure- the official festival selections are displayed for the public in Toronto for four days in May, and past submissions have been used for such purposes as the Launch (at the CBC building in downtown Toronto,) and have been featured in a TV show.
For more information and to submit, you can visit www.m3f.org.
You won't regret getting involved- it's a great experience....I've had so many wonderful experiences with it myself.
