Tui's new development for the Royal Marsden Hospital is the Cancer Campaign website. This pro bono work is designed to fit in with the existing print material for the appeal. The personal style of the site extends beyond the visual design, featuring hand-written appeals and "day in the life" diaries from patients and staff at the hospital.

The aims are to ensure public understanding of the appeals, to encourage and collect donations and tell people about other ways that they can get involved. Working with the Royal Marsden Hospital's own web and fundraising departments, Tui delivered the first phase of the campaign site in February 2004.
