Retro gamers who like a hot mug of tea rejoice – the Manic Miner Heat Changing Mug is here.
An officially licensed design, this Spectrum-inspired mug does pretty much what you expect from the title. When cold, it just has the 'Manic Miner' name on a black mug. But when a hot drink is poured into it, a full cooer scene from the game appears, fading away as our cup cools.
If you fancy one for your work brew, it costs £6.99.
