Thanks Funghy-Fipps for the comments and the light box tip. It certainly sounds like a better solution to buying a light box.
Thank you Smith and hubbabubba. Smith, I have no idea who made that mini (evilBay lot you know) so I would go with what hubbabubba said.
And thank you Garanhir. The tiles have served their purpose, I got a chance to play around with them and I have developed some new ideas.
