Blinkenlighs, LED patches with patterns. Rarely candles.
Not particularly holiday. I do whenever I like or I celebrate (including holidays).
Edit: Only home. Only my bedroom if don't have much time. People call ot weird cause why not living room that others see, but I'm ok with it :)
I find banking apps pretty infuriating. Don't support rooted/custom rom. Too easy to make mistake. Susceptible to 'malware' (ie intent jacking or if the app logs tokens in logcat lol). I use netbanking when needed. For txn logs, mostly SMS works fine.
I find keeping bank account logged in always isn't necessary and just a invitation of hassles.
