Stanley Strum is spending his time in class today building a TARDIS, the time machine from the TV show “Doctor Who.”

“The machine pretends to be a telephone box, but actually it’s an infinite, ginormous, thing on the inside,” he explains.

Strum, a fourth grader, is building this TARDIS out of blocky pixels — kind of like digital Legos — in the world of Minecraft.
