Brandon Wilson is drawing a logo for a number each day this year. He started at 0 on the first of January, and he’ll finish with 365 on the first of January 2014 (or with 364 on the 31st of December. Not sure.) Sadly that means 367 – the largest number whose square’s digits form a strictly increasing sequence – misses out on a logo, but if your favourite number is a natural number at least a couple of units smaller than that, you’re in luck.

Brandon’s blog is NSFS — Not Safe For Synaesthetes — since numbers may appear different to how you imagine them.
