Recently I am considering building a showcase project, perhaps I could demonstrate to future prospective employers, perhaps even just to progress with my own skill building. But I am a little perplexed what is the best option for this, using the underlying core Java I have learnt and continue to learn.
Of course building a small app, or cms using Swing would make sense from my current skillset, but I have been told by wiser developers not to invest time in Swing.
So that redirects me to Grails, Groovy for a web based app, but I wonder how deviated these languages sets are from the core Java.
Any ideas whats the best move? Im really open to any ideas, but please try to think in terms of helping future employment potential, so any new/up-and-coming trends may be the way to go.
