Clip Art has almost been around as long as the internet has and at one point in it's colorful online history was a big deal if you wanted to build a website without any training, or make your MySpace page look 'purdy'.
But alas, time and technology has moved on and our love for the pre-made images used to illustrate any medium has definitely wained.
Now you may look at clip art and think it's all just a load of crap that serves no use to anyone and doesn't deserve to appear on your tablet or smartphone, but that's because you're not being creative enough.
You need to think outside the box, making something crap look cool takes talent, working with a medium no one likes anymore takes serious talent and using a font that was once revered like Justin Bieber (remember him) before everyone went off him is the challenge of champions, like the people who recreated these famous movie posters using nothing but clip art complimented with—what else—Comic Sans.
Sometimes old-skool can still be cool. Respect.
