Making the 12 colors I bought for like 50 dollars more versatile with a syringe as I don't want to buy any more. Faber-Castell Pitt artist pens are great high quality light-fast markers that you can make high contrast scribbles with unless you have every color they sell. Or you could do something like this and get a large amount of shades/intensities out of a single pen. I guess this is a 'art hack' for value maximization... I'll squeeze more key-words into this description later...
