We report an experimental evaluation of Palimpsest, a novel purely-visual programming language. A working prototype of Palimpsest had been developed following a practice-led process, in order to assess whether tools for use in the visual arts can usefully be created by adopting development processes that emulate arts practice. This initial prototype was received more positively by users who have high self-efficacy in both visual arts and computer use. A number of potential usability improvements are identified, structured according to the Cognitive Dimensions of Notations framework.
