Hi Apologies for the cross-posting. A teacher at one of the schools here has developed some Excel spreadsheets for demonstrating various elements of maths. He's essentially programmed a whole interface using macros and conditional formatting to make a highly useable interactive whiteboard maths teaching solution. I'm desperately trying to persuade him to open source it, but... One of the hurdles is that he doesn't believe it can be made to work under OOo with the same look and feel as he's painstakingly developed. I'm certain it can but don't have the necessary skills to undertake the work. He's arguing that the cost of his solution would be far less than the cost of the MS licences and therefore it makes no odds if he sells it; therefore no OOo, no free solution. Poor argument, I know, but if we can prove OOo can do the work, I think he can be persuaded to GPL the remainder. He's offered one module for me to prove it can be done. Any takers?
