In this report we present the solutions to two selected challenges that have been proposed in the 1995 Glasgow GUI-fest. The solutions are defined in the pure, lazy, functional programming language Clean. We have used the currently available version of the Event I/O library version 1.0. The two selected challenges are an object oriented counter viewing program, the Œcounter challengeš and a board game, the ŒExplode challengeš. One interesting aspect in the way we have approached the counter challenge is to first define a very general framework for browser/editors, inspired by a challenge proposed by Emden Gansner. The counter challenge is then defined as an instance of this general browser/editor framework. The Explode challenge can be worked out as a straightforward Event I/O program. It demonstrates the elegance and expressiveness of functional programming.
