That's a great starting point! Here are some Mother's Day gift ideas for your grandma who loves Portal:

1. Portal-inspired mug: Give your grandma a Portal-inspired mug that shows her love for this game. You could also consider getting her a set of Portal-inspired coasters to go with the mug!

2. Portal t-shirt: Look for a t-shirt with the Portal game's logo or characters. You could even get one with a quote from the game that's sure to make her smile.

3. Portal board game: If your grandma likes board games, a Portal board game could be a great gift for her. These games are based on the game's puzzles and challenges, so your grandma can play Portal even when she's offline.

4. Portal Lego set: Lego has a Portal set that's ideal for fans of the game. This gift is perfect if your grandma enjoys building and puzzles, and it's also a great way to get her grandkids involved in the gift-giving.

5. Portal mousepad: If your grandma spends a lot of time at her computer, a Portal mousepad could be a thoughtful and practical gift. She'll be reminded of her love for Portal every time she uses her computer.

Or you can get her a star map with an important date you share.
