Thanks to Rob Chambers for the tipoff to a great free set of tools.
TRIPTICO is a free download, which produces a desktop widget.
It has been developed by David Riley, as a way of offering tools that teachers can customise to their particular subject and year group.
I like a few of the tools in particular, and could see them being of particular use. One of them is a FIND TEN generator, which allows you to create a list of items, with 10 of them being the correct answers. I created one below - e-mail if you'd like a copy - you'll need the TRIPTICO tools in order to use the file...

A list of the current tools - more are in development....
