I really like those pixel puns you make, and you have quite a few now.
Is there a way you can scale them so they become bigger without the pixels becoming blurry (in photoshop its called 'nearest neigbour') because I think the would really be great if the where bigger (like 3 times as big) with pixels that could have come from a Comadore 16 or something.
No not just making them bigger, because then the pixels will still be small, I mean blowing them up so the pixels become those really visible blocks kinda like this:
(Preferances- interpolation: Jagged)
So You still make them like you do and then blow them up slightly so you really see those pixels. maybe tis is to big for your taste but it is something you might want to experiment with there is a lot of design now days that is made kinda in this way (because big pixels are just so cool).
