If your mum is of the geeky persuasion, she might like something a little different for Mother's Day.
Give your mum the stars ... indoors. This projector lamp is a little fiddly to assemble (check the website for an assembly guide), but once you have it up and running, it will fill a darkened room with a stunning light projection of the cosmos.
Anyone who says they don't want to dress up as Wonder Woman in the kitchen is telling lies — and everyone deserves to feel like a superhero, no matter what they're doing — whether it's cooking a delicious beef Wellington...
We don't think this TARDIS bag is, in fact, bigger on the inside — we Earthlings are bound by the laws of physics, after all — but it's capacious enough for a 14-inch laptop or a bunch of gear, and even has a zippered pocket for valuables.
If you've ever wanted to give your mum the moon, this is your chance, with this glorious glowing wall sticker made using photographs of the actual moon. It's available in a bunch of different sizes, too, if the big one's a little too overwhelming.
Maybe you love your mum a whole solar system's worth. Or maybe she just really, really loves space. Either way, Chain of Being's solar system jewellery is lovely. The planets, obviously, aren't to scale, but the distances are, and there are tiny white beads to represent each planet's moons.
Whether it's a cup of relaxing afternoon soup or a giant cup of coffee, nothing is quite as rejuvenating as a hot beverage — and these mugs, stamped with 1s and 0s from old typewriter keys and machinist punches, are one classy way to get it.
We don't think, in all honesty, that this cutting board is very practical as a cutting board; all kinds of food would get all caught in the grooves, making it pretty hard to clean. As a periodic table, though, it's top notch.
Speaking of kitchen science, if your mum's a foodie, you can't go past Niki Segnit's The Flavour Thesaurus. It's not a traditional cookbook; you won't find recipes in between its pages. Instead, it matches hundreds of flavours that go well together, leaving the creative work to the cook.
If you feel like splashing out on something seriously luxe, these realistic, life-sized chocolate skulls are both anatomically correct and utterly delicious. Just remember: 2.5 kilograms is a lot of chocolate. If you don't want quite that much, or don't have quite enough money, this 1.5-kilogram one is pretty great, too.
Looking for something small and sweet? We love fancy soaps. They look pretty and smell nice, and can add a finishing touch to bathroom decor. In particular, we like gamer soaps — like the Legend of Zelda rupee soaps pictured above (US$5 for three); Digital Soap's amazingly lifelike controller soaps and, for the tabletop gaming mum, this set of glittery dice (US$5).
The Antikythera mechanism is a 2000-year-old analogue computer used to calculate astronomical positions. Its configuration of hand-cranked gears is far in advance of what historians believed possible at the time. Its schematic makes a great piece of wall art — and will give you a great story to tell, as well.
